Is there a way to do survival analysis with Emax model in SAS?
It is possible to do the Emax model in logistic regression analysis using "Four- or 5-parameter logistic model", but not sure whether it's feasible for survival analysis.

Hi:
This may be what you want: http://support.sas.com/kb/22/871.html look on the page for this section
"Four- or 5-parameter logistic model
Like the fractional logistic model, these models (also called Emax or Hill models) are for a continuous response bounded between 0 and 1. They can be fit assuming a specified distribution or using quasi-likelihood for a more distribution-free approach. These models have particular nonlinear forms.
How to fit it: Use PROC NLMIXED to define the model form. Specify the desired distribution or define a quasi-likelihood function."
If that doesn't sound like what you want, you might try posting your question in the Analytic Forum for SAS Statistical Procedures: https://communities.sas.com/t5/SAS-Statistical-Procedures/bd-p/statistical_procedures

Hi Cynthia,
Yes. Logistic regression can do such analysis for Emax model, which is the one that you referred. However, I'm looking for similar analysis in Survival analysis. I'll post it to the Analytic Forum for SAS Statistical Procedures.
Thanks,
