Hi all in mail-list,

I calculated the linear regression coefficient using build-in

function regline(), and recognized that the function regline()

is for a linear regression with a constant (i.e. intercept).

So, I wonder that is there any function/script for a linear

regression without intercept, that is, when x=0, y=0?

Further more, are there some functions/scripts which calculate

common statistical errors of linear regression, for example,

RMSE/D (Root-Mean-Square Error/Deviation), R^2 (Coefficient of

determination)?

Thanks in advance!

Best regards

Hui Wu
