Dear Statalisters:
Judith D. Singer and John B. Willet, in their book "Applied Longitudinal
Analysis", Oxford University Press, 2003, present, in pages 225-232,
analysis for nonlinear growth curve using the PROC NLMIXED of SAS, and
explain that, at the time of writing the book, Stata did not have yet the
same capability.
This is also informed at the end of the page: "Stata Textbook Examples
Applied Longitudinal Data Analysis: Modeling Change and Event Occurrence
by Judith D. Singer and John B. Willett
Chapter 6: Modeling Discontinuous and Nonlinear Change",
site http://www.ats.ucla.edu/stat/stata/examples/alda/chapter6 :
"Table 6.6 on page 231.
* Skipped these for now. Stata does not yet do nonlinear mixed models."
Is it possible now to do such analysis in Stata?
Than you for any orientation.
