TABLE 17-11 A Logistic Regression Model Was Estimated in Order to Predict

Short Answer

TABLE 17-11
A logistic regression model was estimated in order to predict the probability that a randomly chosen university or college would be a private university using information on mean total Scholastic Aptitude Test score (SAT)at the university or college,the room and board expense measured in thousands of dollars (Room/Brd),and whether the TOEFL criterion is at least 550 (Toefl550 = 1 if yes,0 otherwise.)The dependent variable,Y,is school type (Type = 1 if private and 0 otherwise).
-Referring to Table 17-11,what are the degrees of freedom for the chi-square distribution when testing whether the model is a good-fitting model?
