We need to be competent with changing ecosystem and think beyond the possible. What is the biggest challenge in doing this? "Unlearning and Learning", we think the current ecosystem is the best. Be it health, finserve, agriculture or mechanical domain, we need to emphasize with the stakeholders, to come up with the strategy to drive. The very evident example here is the quality of life is changing every millisecond. Few decades back the phone connection was limited to few, but today all the millennials are having a mobile phone. Now phone is not just a medium to talk, but are so powerful devices that an innovative solution can be developed on it....

Exploratory Data Analysis using R

Hello Data Experts, Let me continue from my last blog http://outstandingoutlier.blogspot.in/2017/08/object-types-and-visualization-using-r.htmll “ Data Types and Visualization using R” where we discussed Object/Data Types like Vector, List, Factor, Data Frame,   Array and Matrix. I did cover how to have a different graphical representation like Line Graph, Scatter Graph, Pie chart, Bar Graph, Histogram and Boxplot Graph. Let us now move forward with core statistical fundamentals for any statistical problem. We will learn about Exploratory Data Analysis. Why do we need it and how to perform Exploratory Data Analysis (EDA)? Let me first help you understand what it is EDA is important for Data Scientist because it will help us Understand key attributes about the data like Mean, Median etc. EDA will help us visualize if there are any anomalies like outliers. Data visualization help us detect if there is any pattern like direct or indirect relationship between 2 set da...
