Data Science Tip Day#6 - Linear Regression, Polynomial Regression

We will be renaming the R tips to Data Science Tips moving on. Today we will look at Linear Regression, Polynomial & Variable Interactions. Today's stats class was very useful and interesting. Any topic of interest needs practise to master the fundamentals.

Linear Regression
Assume a Linear Equation y = mx+b

• Here m is slope, b is intercept value at x = 0
• Similarly, we use the equation to express relationship between dependent and independent variables
• In this equation y = mx+b, y is the dependent variable. x is the independent variable

For illustration purpose let's construct some datasets with a two vectors (y,x)
