... Methods: Indicator variable was created for death within 4 years of study enrollment. Descriptive statistics are presented within groups defined by death within 4 years or after 4 years, and also for the entire sample population. We include the mean, standard deviation, min and max for continuous va ...

... 4) A survey claims that 9 out of 10 doctors (i.e., 90%) recommend brand Z for their patients who have children. To test this claim against the alternative that the actual proportion of doctors who recommend brand Z is less than 90%, a random sample of 100 doctors results in 83 who indicate that the ...

... The marginal effects are computed as the derivative of the simulated probability with respect to each independent variable. A set of marginal effects is computed for each alternative; thus, for J alternatives, there will be J tables. Moreover, the alternative-specific variables will have J entries, ...

Which is the most appropriate measure of center in this case? 3) Roughly speaking, the standard deviation indicates how far, on average, the observations are from the mean. Do you think that for the data set below the s ...
