st: standard error and significance

[jjc.li@utoronto.ca]

Dear all,

Here's a fomula,

Y=1+Rij/(Si*Sj),

where Rij is a coef. abtained form a regression; Si and Sj are  
obtained form a data set (let's say ten years annual data).

Now, I am going to evaluated Y at the means of Si and Sj. The standard  
errors of Y can be calculated by SE(Y)=SE(Rij)/SiSj. So How could I  
determine if the result of Y is siginificant at 5% level, according to  
its standard error? How to do it by STATA?

Thanks!

Crystal
