The resulting growth rate models are shown to be related to rotations of growth curves. Estimated conveniently through growth curve modeling techniques, growth rate models have advantages above and beyond traditional growth curve models. The proposed growth rate models are used to analyze lon… text/html 2011-12-23T17:43:50-04:00 http://nd.psychstat.org/test (1) Setup a web server.
