Subject: Test for Trend: SAS
Content-Type: text/plain; charset=ISO-8859-1
Hi there, two questions. I'm using SAS for my analysis.
QUESTION ONE: I'm using generalized estimating equations (GEE) for my
analysis and one of my variables has an obvious decrease in trend. Is
there a way to do a "test for trend" using PROC GENMOD?
QUESTION TWO: In the absence of GEE, I'd like to assume independence,
just to get a sense of the trend (I know this is inappropriate, given
the correlated data). I know I can use PROC FREQ to do a "test for
trend" for unadjusted odds ratios but is there a way i can calculate
"test for trend" for ADJUSTED odds ratios?
Thanks in advance!
