In python:#$4.$ Fit hospital$\_$lm model to the training set.

#$5.$ Print the intercept and coefficients of the your model $($e$.$g$.,$hospital$\_$lm$.$named$\_$steps$[\text{'}$regressor$\text{'}].$intercept$\_,$

# hospital$\_$lm$.$named$\_$steps$[\text{'}$regressor$\text{'}].$coef$\_)$

#$6.$ Print regression summary on the training set.

#$7.$ Predict LOS on the validation set and print the first $5$ predicted$/$actual values and residuals.

#$8.$ Print the regression summary on the validation set.

#$9.$ Print R$^2($validation set$)($e$.$g$.,$r$2\_$score$($valid$\_$y$,$ valid$\_$pred$))$

#$10.$ Interpret your results
