Explain why the k-fold cross validation method usually gives a more accurate representation of the accuracy of a classification model than the holdout method.
Added by Glenn P.
Step 1
In the holdout method, we randomly split the dataset into two parts: a training set and a testing set. The model is trained on the training set and its performance is evaluated on the testing set. However, this method can lead to high variance in the performance Show more…

If your goal is to achieve less-biased prediction values, would you rather use leave-one-out cross validation, or k-fold cross validation? Explain your answer based on Bias-Variance tradeoff between leave-one-out cross validation and k-fold cross validation.

What are the reasons why you might adjust your model in ways that increase the bias? [hint: think about training error and sample size.]

Please explain why residuals need to be squared in process of generating OLS coefficients. OLS does not automatically produce unbiased estimates. Please briefly explain the condition that must be satisfied for OLS to produce unbiased estimates.
