Karen: GLM supports the POLYNOMIAL option for repeated measures. The first
polynomial is the linear trend (positive means rising; negative =
declining); 2nd polynomial is quadratic, etc. for 1 fewer trends than you
have points available. One can chose equal spacing between time points, or
specify the spacing.

Subject: test for trend in repeated measures
I nosed around through the menus, including GLM, and could not find a way to
test for a linear trend in repeated measures. I have six contiguous
measures of bone density for 29 people that I want to look for a linear
trend in. I don't have the time series module. Thanks.
