A study used logistic regression to determine characteristics associated with Y =whether a cancer patient achieved remission (1=yes). The most important explanatory variable was a labeling index (LI) that measures proliferative activity of cells after a patient receives an injection of tritiated thymidine. It represents the percentage of cells that are “labeled.” The first table shows the grouped data. Software reports the second table for a logistic regression model using LI to predict
a. Conduct a Wald test for the LI effect. Interpret. b. Construct a Wald confidence interval for the odds ratio corresponding to a 1-unit increase in LI. Interpret. c. Conduct a likelihood-ratio test for the LI effect. Interpret. d. Construct the likelihood-ratio confidence interval for the odds ratio. Interpret.

To collect data in an introductory statistics course, recently I gave the students a questionnaire. One question asked whether the student was a vegetarian. Of 25 students, 0 answered “yes.”They were not a random sample, but let us use these data to illustrate inference for a proportion. (You may wish to refer to Section1.4.1onmethodsofinference.) Let π denote the population proportion who would say “yes.” Consider H0:π =0.50 and Ha:π =0.50. a. What happens when you try to conduct the “Wald test,” for which
uses the estimated standard error？ b. Find the 95% “Wald confidence interval” for π. Is it believable？ (When the observation falls at the boundary of the sample space, often Wald methods do not provide sensible answers.) c. Conduct the “score test,” for which
uses the null standard error. Report the P-value. d. Verify that the 95% score confidence interval (i.e., the set of π0 for which |z|＜ 1.96 in the score test) equals (0.0,0.133). (Hint: What do the z test statistic and P-value equal when you test H0:π =0.133 against Ha:π = 0.133.)
