Statistical Tools for Data Analysis

Business Analytics a fast growing field in developing nations and in India you can see sudden growth of analytics in the last decade. The range of tools go from the simple excel to the more complex ones like statistic etc.  Here, we shall try to see a glimpse of various analytical tools used in the industry also specifically by some companies.

Let’s look at the top analytical tools in the business world

  1.  Excel
  2. SAS
  3. SPSS
  4. Statistica
  5. Salford Systems
  6. KXEN
  7. Angoss
  8. Matlab
  9. R
  10. Weka

Excel : Every business unit have access to MS Excel. This is an excellent analytical, reporting and dash-boarding tool. Excel can handle tables with up to 1 million rows

SAS : SAS is the elephant of analytical industry and it’s been there for long. This tool has been used by most of the important analytical companies of the world. It is most popular irrespective of its high price.

SPSS: This tool is most famous for its GUI based application. It is easy to use and understand. It is point and clicks and has advanced modelling capabilities

Statistica: It is developed by statsoft. Statsoft also has a website online which has most of the statistics concepts neatly explained there. Statistica supports wide variety of analytics technique on the lines of CRISP-DM (Please look up for this one online. This is the bible of any analyst). The GUI though is not so user friendly here

Salford Systems : Provides predictive analytics and data mining tools for the industry. It specialises in regression algorithms

KXEN : They are specializing on automated analytics. Their products are comparatively easy to use. The result however is rather difficult to understand which a drawback is for them

Angoss: They have advanced decision tree algorithms. The GUI is easy to use

Matlab:  It has more of mathematical applications. They have add on features which helps to make the organisation fine tune the tools to specific areas of functionality.

R : This is an amazing tool for statistical computing and graphics(Graphics after Matlab). This is an open source ware and is widely used by the academic community. This is updated by the user community and can find 800 and odd packages for various functionalities.  You can find packages for almost anything and everything. You have many GUIs available with R, Rattle is one of them for statistical analysis.

Weka: This is another free ware like R. The software is written in Java and contains a GUI for interacting with data files and have visual effects and graphics.

That was in a nutshell the tools used and the important companies in the analytical industry. This was only a gist. It’s a booming field for the coming years in India. Let’s leverage the maximum from this. ATI will be a part of this humbling journey to empower professionals.

Neural Network Image

The Simple logic behind Neural Network

The prediction of time series using neural network consists of teaching the net the history of the variable in a selected limited time and applying the taught information to the future. Data from past are provided to the inputs of neural network and we expect data from future from the outputs of the network.

An example of using neural networks for prediction: In today’s economy, most companies need to monitor their business expenses regularly and forecast accurately. They typically have a record of their business expense in the past. But most companies have multiple departments, and each of them have a different need of expenses. A general ARIMA time series model would require the company to forecast the expense for each of the department separately. Neural Network will help us to forecast the expense of company considering all the department and any other variables that are included.

How To Use Google Search More Effectively

Google is the biggest search provider for years now and it will remain the same for the upcoming decade as well. Google Search Engine contains so many resources that one can only imagine to exploit each and every one.

For this purpose we have gathered some of the best google search tricks from the web, although we have covered almost all aspects in this post but i am sure there will be number of other things which may not be mentioned here. Let’s dive into the golden search tricks to make a good use of this huge search provider.

Shortcuts

Use these shortcuts to make your Google searches even faster.

  1. I’m Feeling Lucky: If you’re an expert searcher, use this button on the Google search page to get automatically directed to the first web page that would normally show up in a list in a general search.
  2. “Better than” and “reminds me of”: This weird little tip will help you find comparisons. Just type in either search term and then a keyword, all enclosed in quotation marks.
  3. cache:: Use this shortcut to show a web page in its cached version.
  4. related:: Type in a website after related: to find related sites.
  5. Shortcut for spellcheck: Don’t bother going to a dictionary website to see if you spelled something correctly: just enter it into Google’s search bar, and the “did you mean…” suggestion will pop up with the correct spelling.
  6. Google Blog Search: Blog Search is another quick way to jump to blog posts only.
  7. Set up iGoogle: Personalize your Google homepage so that it contains links to your favorite feeds and research pages.

  1. They don’t spend much time in developing traditional algorithms anymore (e.g. search engine). They don’t reinvent the wheel, they re-use existing algorithms, even though they could do a better job by re-inventing these old algorithms. But they think at significantly improving existing algorithms (e.g. search engine), both from a business and technical point of view. Sometimes they even do a bit of hacking and reverse engineering.
  2. They spend a lot of time identifying useful data sources (most of the time, external sources), and checking how they could be exploited and leveraged.
  3. They develop meta algorithms: that is, algorithms that rely on lower level techniques such as taxonomy creation, spell check, keyword associations, news feed aggregation etc. They blend these low level algorithms to produce automated high end products.
  4. Modern data mining is to old data mining what coding in Python is to coding in assember, Perl, or C.
  5. These data miners don’t call themselves data miners anymore: they are statisticians, scientists and data miner all at the same time, combining all these roles in one person. Indeed, they are even business people and sales guys (selling internally – to their boss and employees reporting to them, and externally – being invited at important sales calls by their company).
  6. Many times, they succeed not by analyzing data, but by applying analytic thinking to business problems. Example: we’ve increased our signups by a factor 3 on our network thanks to analytic thinking – however no data was leveraged to get to the action resulting in signups improvement.
  7. They sometimes develop great products without having to produce one line of code: our news feed optimizer is a good example of a technology that was developed without writing any code, but instead relies on widgets to distribute the news, manual selection of good feeds, and intelligent use of feed aggregators such as twitterfeed or feedburner.
  8. They find the information they are looking for on the web (and more and more from social networks as opposed to Google), but not from books nor University training.
  9. They are working on algorithm speed optimization and scalability, even (and especially!) when developing prototypes.
  10. They are thinking so much out-of-the-box, that they are not generally a good fit for the corporate world. Instead, they become successful entrepreneurs.
  11. They are domain experts more so than coding experts. But they are also generalists across many fields and many tech skills (e.g. all of them are very familiar with SQL and R). At the same time they have deep expertise in a few (one or two) specialized domains and programming languages.

A simple Excel Dashboard for a cause

We are in world where we are accustomed of having information at their fingertips. We also have the need to identify key performances of our company at a glance. This is where we have the need to create or build dashboards. There is no better platform than MS Excel for building a simple dashboard with simple tools. A dashboard consolidates information that is pulled from multiple data sources and transforms the information into a visually rich interactive chart.

The following video demonstrates a simple dashboard created for the Autism Society of India.

Tips for Facing an Interview

Body language:
The body language plays a very important role in an interview. This implies that when one makes any positive statements, those movements should be supported by his/her body language. When entering the interview room, one should not have a tough look and a smile with tension in mind. Even the way one enters the room and sits is noticed. Actually one should enter with a calm smile on face and a stiff body posture which shows that he/she is not nervous at all and has a positive friendly attitude.This makes the interviewer also to feel open and become friendly at the first sight which in return increases one’s chances to get through the interview.

Punctuality:
It is very important to be on time for an interview. Instead, one should reach an hour early which is much better than arriving a few minutes late and will put a bad impression on the interviewrs. Also, if one reaches early, he/she gets enough time to relax your mind, put all the scattered thoughts in the mind together, get used to the environment and lessen the nervousness. Moreover, it gives time to one to have a final check on yourself.

Greet the Interviewers:
‘The first impression is the last impression” is one of the oldest and important idiom used by us. As and when one enters the room for interview, everybody looks at his/her personality, facial expressions and that is the time when the interviewer has the first impression about you. Therefore, one should greet the interviewers by taking his/her last name and if one does not know their names, one should first check it on the reception before going in the interview room.

Handshake:
I know that most of us do not consider or are unknown that the way you shake hands with the interviewer also plays a very important part in an interview. To form a positive impression one should do a firm handshake, which shows his/her confidence level. Also, when one is shaking hands, one should make eye contact with the person he/she is shaking hands with.
If one gives a weak handshake that shows that he/she is weak and not confident enough to take up the responsibilities at work. Also, if the handshake is too hard and by chance it hurts the interviewer a little, it puts an impression that he/she is Dominant.
One should shake hands for 3-5 seconds maximum.

Maintain Eye contact:
One should try to make an eye contact with the interviewer especially when you are having any conversation with the interviewer. If one tries to avoid the eye contact, this makes the interviewer believe that there is something fishy and he/she is hiding something. Hence, that gives them an impression that the interviewee is unfaithful or untrustworthy.
Therefore, one should be confidently talking with the interviewer with proper eye contact. But that does not at all mean that one should stare at the interviewer.

Way you Sit:
I understand that it sounds a little different but yes the way one sits in the interview room and when do you sit also shows your many things about your personality.
One should not sit immediately after entering the interview room but wait for the interviewer to offer him/her a seat. If not offered a seat by the interviewer, one should take permission to take a seat. This is because if one sits without being offered or without asking, that makes the interviewer perceive that he/she is arrogant, over-confident, nervous, etc. which can act against you in the interview.

Talk Precisely:
One should be precise on what he/she is talking as the rule says that the interviewee should talk 1/3rd of the time. One should let the interviewer talk at the beginning about what are the requirements, about the company details, what job profile are they looking for, how they want their employees to be in the organization,etc. One should always keep in mind that when the interviewer is doing the above talk, he/she should not at all be giving a negative message by their body language instead he/she should have a positive body language towards whatever the interviewer explains and it is much more beneficial for the interviewee to ask questions to show that he/she is quite interested to know more about the organization. It is much better than only speaking about yourself continuously.

Be Confident at the End:
At the end of the interview also, one should be energetic and should have a firm and energetic handshake before leaving the interview room. One should also thank the interviewer as well at the same time while shaking hands before leaving in the same way as done when entered the room athis gives an impression that you are friendly and also leaves a good impression on the interviewers. One should not get up from the seat and show hurry in leaving the room at the end. Instead, he/she should wait for the interviewer to show that it is over now.
Even if one thinks that the interview did not go well and he/she is sure that he/she may get rejected 99.9% , still one should never let them get the impression that he/she is discouraged sthe reaction.

Thanking:
One of the most essential part is thanking the interviewer at the end for their time and also sending a small ‘thank you’ mail after leaving the same day. In this mail one can write precisely the important parts of the conversation at the time of interview and again emphasize on your skills which can bring benefits to the organization and the position you have applied for.
