1. Enter the data from Exercise 6.1 above into SPSS, Stata, or R. Analyze these data with the counts as the dependent variable and group as the independent variable. How does the regression coefficient for the values you computed as part of Exercise 6.1 compare with the results from this analysis? Open the NYS Wave I data file (nys_l.sav, nys_l_student.sav, or nys_l.dta) to complete exercises 2–4. Make sure to select a variable from the dataset to be the exposure/offset variable when appropriate. When selecting independent variables, keep in mind the guidelines for selecting covariates that you learned in prior chapters (e.g., be mindful of multicollinearity).
