st: econometric analysis of proportions

Subject   st: econometric analysis of proportions

I am interested in tracking changes in proportions over time and testing
for trend effects.  I have a categorical variable with 11 categories that
is measured in aggregate data annually.  I want to do some tests for
positive or negative trends in the shares in the categories.  I know the
count of cases in each category and year and the overall annual total.
Does anyone have suggestions on how I can model this?
