I am struggling with one calculation and I am not sure how to solve it. Maybe one of you can help me:

I have applied a weighted linear regression. Now I need to know the relative standard deviation of the regression line sx,y (%).

How do I do it. For calculating relative standard deviation the formula (sd/mean)*100 is used. What about the regression line`?

For example I obtain the below listed results:

Model R R Square Adjusted R Square Std. Error of the Estimate
1 .997 .995 .995 .00673

What should I do with the std error of the estimate? Simply multiply the value *100 or do I need anything else?

Thanke you for your help.
