Python

Consider a data set containing four data points (1, 2.1), (2, 2.8), (3, 4.2), (4, 5.3). Each data point is represented by its x and y coordinates.

A. Use the OLS method to compute the line of best fit for the data set. You must manually compute m and b.

B. Compute the sum of squared residuals between the actual y values and predicted y values using the line obtained in part A.
