Linear Regression

Ways to reduce residuals further:
1. Add more important variables to the model
2. Use time series if your residuals are related over time

M_hi_full_res <- residuals(model_M_hi_full)

M_hi_full_res <- xts(M_hi_full_res, order.by = dates_train)

hist(M_hi_full_res)
plot(M_hi_full_res)
