WebApr 1, 2024 · Other methods using alternative link functions are also available, such as the multivariate probit model using the probit link function, which can be implemented in PROC GLIMMIX, or by other methods such as the Chib and Greenberg formulation [9]. This manuscript will focus on the GLMM model using the logit link function, as the coefficients ... WebStandard errors on the inverse linked scale are computed by the delta method. The GLIMMIX procedure applies the inverse link transform to the LS-mean reported in the Estimate column. In a logistic model, for example, this implies that the value reported as the inversely linked estimate corresponds to a predicted probability that is based on an ...
