Project 4: The California Bureau of Prison's board of directors wanted to be able to predict parole violations (DV) by prison punishment record (IV) and prior criminal record (IV). Information on 4000 inmates of the state penitentiary system from 1989 - 1994 records were scrubbed. The data collected is provided in the accompanying excel table (parole data set.xlsx). Columns are coded as follows. Incidence of Parole Violation, by punishment record and prior criminal record for 4000 inmates of California State penitentiary system from 1989- 1994. Punishment record in prison 0=None, 1=1-2 times, 2=3 or more times Prior record 0=none, 1=fine/probation, 2=reform school, 3=jail, 4=penitentiary Subsequent parole violation 0=No, 1=Yes */ Number of inmates Use the Check list (Table 10.16) found on page 482 of the text book and the information provided below to write a report on the Logistic Regression for the data set provided. (Hint: Report should be similar in scope to \"Results at the end of Chapter 10\".
