when might overfitting occur - Answer- 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 - Answer- less data is required; less chance of insignificant factors and easier to interpret what is forward selection - Answer- 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 ...
