Using the date provided, develop the projection for wins of the 15 year using the following models:  1. Linear regression  2. Moving Average using a N= 4, and N=6  3. Weight Moving Average with (45%, 30%, 25%)  4. Exponential Smoothing with alpha =20%  Calculate the MAD for each model and determine which model is more aligned with the trend of the values.  Calculate R and F for the Linear regression and make your interpretation.

Calculate R and F and T statistics and interpret them.

Run test for multicollinearity, autocorrelation, and Heteroscedasticity. Comment on the outcomes.
