1. If there are variables that need to be used to control the bias selection in the model, they should be forced to be in the model and not be part of the variable selection process. - ANS True 2. Penalization in linear regression models means penalizing for complex models, that is, models with a large number of predictors. - ANS True 3. Elastic net regression uses both penalties of the ridge and lasso regression and hence combines the benefits of both. - ANS True 4. Variable sele...

ISYE 6501 - Midterm 2 when might overfitting occur when the # of factors is close to or larger than the # of data points causing the model to potentially fit too closely to random effects Why are simple models better than complex ones less data is required; less chance of insignificant factors and easier to interpret what is forward selection we select the best new factor and see if it's good enough (R^2, AIC, or p-value) add it to our model and fit the model with the current set of ...
