Estimates by Subject and Difference Between Subjects Tests Using PROC PHREG [URGENT]

DocLog — Mon, 17 Apr 2023 19:15:12 GMT

Hello and Good Day,

I am conducting a choice-based conjoint analysis (experiment with 3 blocks - each with a unique treatment) utilizing PROC PHREG. I have a total of over 200 respondents.

There are two things I would like to accomplish and get guidance on:

1. Am I able to generate parameter estimates for each single participant (i.e. generate parameter estimates at the individual level in addition to the aggregated estimates) using PROC PHREG? If so, how do I go about doing so (What's the SAS Code?)?

2. I want to compare generated parameter estimates between the groups and test for significant differences between 2-category factors and between 3 to 4--category demographic factors. How best can I do this having utilized PROC PHREG (What's the SAS Code?) ?

Here is the code I used to generate my current results:

%phchoice(on) 
PROC PHREG data=LMLData outest=COEF; 
strata DDM Set; 
class DS (ref='1') DW (ref='1') WG (ref='1')/ param=ref;
model Choice*Choice(2) = DS DW WG / ties=breslow; 
run; 
%phchoice(off)

I moved your question to the Statistical Procedures community, so that those listening in on it will be alerted.

Please do not post the same question multiple times, keep everything in one thread.
