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 predicta. 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.
For the horseshoe crab data , fit the logistic regression model for π =probability of a satellite, using weight as the predictor. a. Report the ML prediction equation. b. Findat the weight values 1.20, 2.44, and 5.20kg, which are the sample minimum, mean, and maximum. c. Find the weight at which. d. At the weight value found in (c), give a linear approximation for the estimated effect of (i) a 1kg increase in weight. This represents a relatively large increase, so convert this to the effect of (ii) a 0.10kg increase, and (iii) a standard deviation increase in weight (0.58kg). e. Construct a 95% confidence interval to describe the effect of weight on the odds of a satellite. Interpret. f. Conduct theWald or likelihood-ratio test of the hypothesis that weight has no effect. Report the P-value, and interpret. Note: you can get the data in the R package "icda" which is named by "horseshoecrabs".
A study in Florida that stated that the death penalty was given in 19 out of 151 cases in which a white killed a white, in 0 out of 9 cases in which a white killed a black, in 11 out of 63 cases in which a black killed a white, and in 6 out of 103 cases in which a black killed a black. The table shows results of fitting a logit model for death penalty as the response (1=yes), with defendant’s race (1=white) and victims’ race (1=white) as indicator predictors.a. Based on the parameter estimates, which group is most likely to have the “yes” response? Estimate the probability in that case. b. Interpret the parameter estimate for victim’s race. c. Using information shown, construct and interpret a 95% likelihood-ratio confidence interval for the conditional odds ratio between the death penalty verdict and victim’s race. d. Test the effect of victim’s race, controlling for defendant’s race, using a Wald test or likelihood-ratio test. Interpret.
