Textbook Question
Chapter 5, Problem 80E

Anabolic steroid abuse has been increasing despite increased press reports of adverse medical and psychiatric consequences. Medical researchers studied the potential for addiction to testosterone in hamsters (Neuroscience [2004]: 971–981). Hamsters were allowed to self-administer testosterone over a period of days, resulting in the death of some of the animals.

The data below show the proportion of hamsters surviving versus the peak self-administration of testosterone (μg). Fit a logistic regression equation and use the equation to predict the probability of survival for a hamster with a peak intake of 40 μg. (Hint: See Examples 5.24 and 5.25.)

Find the pvalue for the intercept and state the correct representation of the related logistic regression model?
The following table contains statistics from a logistic regression analysis for a study on intravenous drug use among high school students in United States. Drug use is characterized as a dichotomous variable, where 1 indicates that an individual has injected drugs within the past year and 0 that he or she has not. Factors that might be related to drug use are instruction about the HIV in school (1 represents "had HIV education" and 0 represents "did not have HIV education"), age of the student (in years), and gender (1 represents male and 0 represents female). Statistics in the table are estimated coefficients of the logistic regression model and p-values for testing the significance of the coefficients. Choose proper answers using statistics in the following table.  (THERE MAY BE MORE THAN ONE CORRECT ANSWER) Variable Coefficient p-value Intercept (Constant) -0.164 0.078 HIV instruction 0.019 0.928 Age 0.064 0.036 Gender 1.032 0.014…
In logistic regression, the predictors are dichotomous, and the outcome is a continuous variable.

  • For the 23 space shuttle flights before the Challenger mission disaster in 1986, The following table shows the temperature (◦F) at the time of the flight and whether at least one primary O-ring suffered thermal distress. Use logistic regression to model the effect of temperature on the probability of thermal distress. Interpret the effect. Estimate the probability of thermal distress at 31◦F, the temperature at the time of the Challenger flight. At what temperature does the estimated probability equal 0.50? At that temperature, give a linear approximation for the change in the estimated probability per degree increase in temperature. Interpret the effect of temperature on the odds of thermal distress. Test the hypothesis that temperature has no effect, using (i) the Wald test, (ii) the likelihood-ratio test.

    The National Survey of Drug Use and Health is a large annual cross-sectional survey of drug use in the United States. Using data from this survey, researchers wanted to assess the relationship between region in the country (Northeast, Midwest, South, and West) and past-month marijuana use among 18-25-year-olds. They obtained the following logistic regression model from the data: 1)What are the log odds of past-month marijuana use among 18-25-year-olds in the Midwest? 2)What is the probability of past-month marijuana use among 18-25-year-olds in the Northeast? 3)The odds of past-month marijuana use for 18-25-year-olds in the South is _______ times the odds of past-month marijuana use for 18-25-year-olds in the Northeast.

    The dating web site Oollama.com requires its users to create profiles based on a survey in which they rate their interest (on a scale from 0 to 3) in five categories: physical fitness, music, spirituality, education, and alcohol consumption. A new Oollama customer, Erin O'Shaughnessy, has reviewed the profiles of 40 prospective dates and classified whether she is interested in learning more about them. Based on Erin's classification of these 40 profiles, Oollama has applied a logistic regression to predict Erin's interest in other profiles that she has not yet viewed. The resulting logistic regression model is as follows:   For the 40 profiles (observations) on which Erin classified her interest, this logistic regression model generates that following probability of Interested.     Probability of     Probability of Observation Interested Interested Observation Interested Interested 35   1 1.000 13   1 0.412 21   1 0.999 2   0 0.285 29   1 0.999 3   0 0.219 25   1 0.999 7…
