In the displayed output of PROC LOGISTIC, the "Odds Ratio Estimates" table contains the odds ratio estimates and the corresponding 95 Wald confidence intervals. For continuous explanatory variables, these odds ratios correspond to a unit increase in the risk factors. To customize odds ratios for specific units of change for a continuous risk factor, you can use the UNITS statement to specify a list of relevant units for each explanatory variable in the model. Estimates of these customized. For example, the odds ratio of 2.8 in the "Exp(LogOR12)" row indicates that the odds of brand 1 being in lower taste categories is 2.8 times the odds of brand 2 being in lower taste categories..

Unlike PROC LOGISTIC, the GENMOD and GEE procedures do not provide odds ratio estimates for logistic models by default. When fitting a model in these procedures, odds ratios are only possible when the response is binary or multinomial (DISTBIN or DISTMULT) and the link involves a logit function (LINKLOGIT or LINKCUMLOGIT). The s h coefficient represents how much s and h change per unit-increase in H E I G H T and S E X, respectively. Given S E X 0 for males and S E X 1 for females, we can construct regression equations for males and females by substituting in these (0,1) values to see this relationship explicitly. If we compare the predicted counts at these two levels of math, we can see that the ratio is (10.756912.1267) 0.887. This matches the IRR of 0.994 for a 20 unit change 0.99420 0.887.

12.3 - Log-binomial Regression If modeling a risk ratio instead of an odds ratio and the risk ratio is not well-estimated by the odds ratio (recall in rare diseases, the OR estimates the RR), SAS PROC GENMOD can be used for estimation and inference. Skinner, Li, Hertzmark and Speigelman, 2012) PROC GENMOD can also be used for Poisson regression. The odds ratio is defined as the ratio of the odds for those with the risk factor () to the odds for those without the risk factor (). The log of the odds ratio is given by In general, the odds ratio can be computed by exponentiating the difference of the logits between any two population profiles.. Table 45.9 displays the log odds ratio structure keywords and the corresponding log odds ratio regression structures.
