OMSA Midterm 2 Exam Questions With 100% Verified Answers. Overfitting - answerNumber of factors is too close to or larger than number of data points -- fitting to both real effects and random effects. Comes from including too many variables! Ways to avoid overfitting - answer- Need number of factors to be same order of magnitude as the number of points - Need enough factors to get good fit from real effects and random effects Simplicity - answerSimple models are better than complex. When ...
