my_functions_pkg.supervised_regression.

model_cv_stats

(X, y, test_size, random_state, alphas, cv)

• OLS, RidgeCV, LassoCV, ElasticNetCV
• prints: best alpha, train R^2, test R^2, MAE, MSE, RMSE, MAPE
• returns: df of the cv stats

predictions_df

(X_test, y_test, y_preds)

• returns predictions df and plotly express fig object
• data frame = X_test.copy() + y_true + y_preds + residuals + abs_residuals
• descending order by abs_residuals to view highest model mistakes made & index

plot_sced_test

(df, target, features)

• checks homoscedasticity assumption with plots

top_corrs

(df, column, n=10)

• returns top (n) absolute correlated feature vars vs. target var

plot_top_corrs

(df, column, n=10)

• plots the topp_corrs() using a facet grid

tukey_outliers

(df, var)

• prints outliers at each threshold (1-5)

print_vif

(feature_df)

• check multicollinearity assumption; prints VIF for each feature in feature_df
