The standard error of Rij will be accessible after the rgression as -di _se[Rij]- which , according to your formula, is what you need...

```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
