How to use ApproxStdErr from Nonliear model in a Tukey analysis?<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />I am using a 4p nonlinear model to get the inflection points of curves defined by my data, theta4. I would like to then run something like a Tukey analysis to determine if there are significant differences between these inflection points. I have been looking for a way to pass the ApproxStdErr from the 4p model but have not found a solution. It seems to me that this should be a fairly common situation and would appreciate any guidance in how it should be solved.

Re: How to use ApproxStdErr from Nonliear model in a Tukey analysis?Richard,
If you are fitting your models using the non-linear platform with a grouping variable for your different "groups" then there is an option called compare estimates that utilizes Analysis of Means to compare the parameter estimates across the groups.
