st: VWLS for Trend Analysis

[jasonm@ucla.edu]

I have rates (=injuries/time) and their accompanying confidence  
intervals for a 12 month period (ie 12 rates). I do not have the raw  
data. I only have the point estimates and their accompanying CIs.
Is -vwls- a good approach to see if a trend is statistically  
significant (the point estimates have already been plotted)? Does  
-vwls- have any kind of eform option for the coefficients (since I  
took the log of all the variables)?
