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

question 96

Multiple Choice

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,which of the following is the correct expression for the estimated model?

• A)_{Y = -27.118 + 0.015 SAT - 0.390 Toefl550 + 2.078 Room / Brd}
• B) = -27.118 + 0.015 SAT - 0.390 Toefl550 + 2.078 Room / Brd
• C)ln (odds ratio)= -27.118 + 0.015 SAT - 0.390 Toefl550 + 2.078 Room / Brd
• D)ln (estimated odds ratio)= -27.118 + 0.015 SAT - 0.390 Toefl550 + 2.078 Room / Brd

A scale that measures weight or force by the stiffness of springs.

Hooke's Law

A principle stating that the force needed to extend or compress a spring by some distance scales linearly with respect to that distance.
