1. What is Goodness-of-Fit? 2. Name three common methods for testing Goodness-of-Fit. 3. What is the Method-of-Moments? 4. What is Maximum Likelihood Estimation? a. How are the values for an MLE comparison computed? 5. What is Chi-Squared Goodness-ofFit? a. What is different about what a Chi-Squared Goodness-of-Fit test is usually used for versus MOM and MLE? b. What are its limitations? 6. Which method is preferred? Why? 7. What is the difference between the Equal-Bin-Width and the Equal Average Observation Methods? a. In the Equal Average Observation Methods, how equal do the observations need to be? 8. Is one better than the other? Why? Under what condtions? 9. What are Probability Plots? 10. What is the Anderson-Darling Test?
