Marginal model
WebMarginal model plots for single predictors (or even unrelated variables) can be generated through placement in the optional varlist in the varlist() option. The generate option makes mmp save the lowess estimates for the model and alternative lines as variables for each of the produced plots.

In statistics, marginal models (Heagerty & Zeger, 2000) are a technique for obtaining regression estimates in multilevel modeling, also called hierarchical linear models. People often want to know the effect of a predictor/explanatory variable X, on a response variable Y. One way to get an estimate for such effects is through regression analysis. WebApr 24, 2002 · We fit the ordinal estimating equation model with initial values of marginal mean parameters set as the parameter estimates from the preanalysis. Then we perform an analyst-driven version of backward selection, which selects between included item by covariate interactions according to both scientific and statistical significance. (c)

Webway to obtain the estimates is by using a Cox model. To allow for non-proportional effects of FLC it was entered as a strata in the model, with age and sex as linear covariates. The assumption of a completely linear age effect is always questionable, but model checking showed that the fit was surprisingly good for this age range and population.
