In this tutorial we will try our hands on a very basic 2 variable linear regression using R. We will also learn how to interpret output given by R and tryout various visualizations required for interpreting simple Linear regression.
In this tutorial we will discuss about structure of Linear regression and how a Linear regression Equation is constructed for 2 variable model.
This Tutorial talks about basics of Linear regression by discussing in depth about the concept of Linearity and Which type of linearity is desirable.
The Tutorial / Article talks about Future trends in Retail Analytics and touches upon how customer data in combination with data science can help and how technology can help in finding solutions to few fundamental problems in Retail Industry.
This tutorial talks about the importance of Testing set and Validation sets for predictive analytic algorithms and different techniques which can be wisely used to get a reliable measure of accuracy.
This tutorial talks about various measures of accuracy in in various predictive analytics and machine learning scenarios. It also talks about potential pitfall of over fitting resulting in memorization vs the learning which is desirable.
This R Tutorial builds on the previous R tutorial and arms you with few more fundamental analysis tools for capturing essence of data. This will go a long way in understanding the data more.
