Question

As a data scientist, you are supposed to build a multivariate linear regression (MLR) model that might be used to predict the Stock Price Index (dependent variable) based on two independent variables namely Interest Rate and Unemployment Rate as they are shown in the mlr_dat dataset.

Find the intercept b and the coefficient Wi. Compare and show side by side to see how close your MLR model prediction.
