Dear SAS users
I'd like to study growth curves. I have weight data points for several individuals (several data points per individual - at different ages) and I'd like to retrieve from the growth curve (which is not linear) parameters such as: growth velocity, age at which a plateus is attained etc... I'll then compare these different parameters among the studied individuals.
Gompertz curves could be appropriate (with the NLMIXED procedure) but I really had troubles designing the adequate procedure. Could you please help me here?
Thanks a lot in advance!
Best
Marie
