Structural Models for Two or More Groups

SEPATH provides a very simple method for specifying models for several populations, or groups. Each model is input as a separate unit of code. Models are specified in exactly the same way as they are for a single group. Path coefficients that are constrained to be equal across groups are given the same coefficient in all groups. The model is input in the following form for two groups:


The system is extended in the obvious way for models for more than 2 groups.
