4.3. Supervision of defendants on pretrial release is thought to reduce the chance that defendants will flee the community. A government agency funds a small study to examine whether supervision affects pretrial flight (flight 1, no flight = 0) and reports the following logistic regression results: VARIABLE Age (years) Sex (1 male, 0= female) Severity of offense scale (0-10) Number of prior felony convictions SE -0.01 0.02 0.67 0.25 0.21 0.03 0.35 0.09 Number of contacts with supervision caseworker Constant -0.13 0.03 -0.52 (a) Calculate and interpret the odds ratio for each of the independent variables. (b) Can the government agency conclude that supervision in the form of contact with a caseworker has a statistically significant effect on pretrial flight? Explain why. (c) If the agency reports that the -2LLull is 653.2 and the -2LL full is 597.6, can it conclude that the model is statistically significant? Explain why.
