OMSA Midterm 2 Exam With Complete Solutions Latest Updated Graded 2023/2024. 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 - Answer- Simple models are better than complex. When fewer factors exist, less data collection is required -- less chance for including factors that are not significant. Another reason for variable selection! DOE - ...
