Question

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.” Table 1 shows the grouped data. Software reports Table 2 for a logistic regression model using LI to predict π = P(Y = 1).

Using information from Table 2, conduct a Wald test for the LI effect and Interpret.
Using information from Table 2, construct a Wald confidence interval for the odds ratio corresponding to a 1-unit increase in LI and interpret.
Using information from Table 2, conduct a likelihood-ratio test for the LI effect and interpret.
Using information from Table 2, construct the likelihood-ratio confidence interval for the odds ratio and interpret.
