Show me your fingers Do not shout out the answer, or your classmates will follow what you said. Use your fingers One finger (the right finger) = A Two fingers = B Three fingers = C Four fingers = D No finger = I don t know. I didn t study
What is one of the important goals of support vector machine? A. To optimize the geoplane that separates the classes. B. To generate hypergeometrical link function for regression analysis. C. To optimize the hyperplane that classifies observations into proper groups. D. All of the above
In one of the leafs (partitioned group) of a tree, there are 9 males and 1 females. According to GINI, this group is A. Highly impure B. Highly pure C. Neither pure nor impure; insufficient information
Which of the following statements about the leaf report is UNTRUE? A. It is based upon the nested-if logic. B. It shows interactions of variables C. The probability of each scenario is the same as the p value in hypothesis testing.
What of the following about the ROC curve is UNTRUE? A. It is originated from Signal Detection Theory during WWII. B. The area under the curve indicates the predictive accuracy. C. When the AUC value is .6 or above, it is considered acceptable.
Which of the following statement is TRUE? A. If the outcome variable is categorical, LogWorth (the likelihood ratio of chi-square) is reported. B. LogWorth is the inverse of the p value. C. Like the p value, a lower LogWorth is better. D. LogWorth is a partitioned criterion based on impurity.
In JMP if you uncheck informative missing before generating a partition tree, what would happen? A. The missing data will be deleted in a listwise way. B. The missing data will be deleted in a casewise way. C. The missing data will be imputed.
Which of the following is NOT an option in SPSS s classification trees? A. C4.5 B. CHAID C. QUEST D. CRT
Which of the following is NOT a drawback of SPSS s classification trees? A. The graphs of JMP are dynamic and interactive whereas the counterparts of SPSS are static. B. The interactive model outline in SPSS shows much less details than the tree in JMP. C. The hierarchy of the SPSS tree might not correspond to the rank of predictor importance. D. Neither viewer nor model outline allows tree-pruning.
