st: Trend Test for Rates

[jasonm@ucla.edu]

I would like to see if there is any kind of trend over a 12 month period.
I have rates (injuries/time) and their accompanying confidence  
intervals for each of the 12 months (ie 12 rates).
Would vwls be a good approach to look for a trend? Does vwls have any  
kind of eform option for the coefficients (since I took the log of all  
the variables)?
