Incidence rate ratio example
WebFor example, the AGE=1, CAR=SMALL population is identified in the model by β 0 + β 3 + β 4, that is the intercept plus the third (small) CAR parameter plus the first (1) AGE parameter. This provides the parameter coefficients needed in the ESTIMATE statement below. WebOne estimates the RR with a log-binomial regression model, and the other uses a Poisson regression model with a robust error variance.

WebIncidence Rate Ratio Interpretation. The following is the interpretation of the negative binomial regression in terms of incidence rate ratios, which can be obtained by nbreg, irr after running the negative binomial model or by specifying the irr option when the full model is specified. This part of the interpretation applies to the output below. WebThe incidence rate ratio for a binary predictor variable is simply the ratio of the number of events of one category to the number of events in the other category. For a categorical variable with more than two categories, the …
