Linear Regression

The values of 2 variables X and Y are given below. Here X is the predictor variable and Y is the response variable.

X 25 30 35 40 45

Y 5 260 480 745 1100

Build your regression model using the following 3 methods.

a) Closed form solution using only the mean of x, y, x*y, x2 variables.

b) Closed form solution using the correlation coefficient between x and y variables and

the standard deviation of both variables.

c) Python using Scikit-Learn and Statsmodels libraries.

Make sure that your answers are the same using all the 3 methods.
