Why is Adjusted R preferred to R to assess the fit of a regression model? Because R² substantially underestimates the variability of the dependent variable accounted for by the independent variables Because R² measures a less relevant type of model fit than adjusted R² Because R² always increases when variables are added to the model Because R² does not account for the possibility of the non-normal distribution of the dependent variable.

Why is RMSE generally the preferred performance measure for regression tasks? A. Because it gives an idea of the average percentage deviation of the predictions from the actual values. B. Because it gives an idea of the average absolute deviation of the predictions from the actual values. C. Because it gives an idea of how much error the system typically makes in its predictions, with a higher weight given to large errors. D. Because it gives an idea of the average deviation of the predictions from the actual values.
1.) When and Why do we use Proportional model, Binomial model, and Poisson regression model? 2.) How and why are degrees od freedom infleunced by each of these models?
What are the benefits of using all-subsets regression versus stepwise regression when it comes to data analysis?
In terms of statistical analysis, explain why all-subsets regression is preferable than stepwise regression.
Why use LASSO shrinkage methods for linear regression? Select ALL that are correct. They allow for greater model interpretability. They increase the prediction accuracy of linear regression on training data. They slightly decrease bias and can substantially decrease the variance of the model. They slightly increase bias, but can substantially decrease the variance of the model.
Why and why do we use the Binomial, Poisson, and Proportional models of regression? Explain how and why degrees of freedom are included into each of these models.
