regression with error bars [message #70719]

Hello

I have two columns of data y (with errors Err+ and Err- for each data
point) and x (with Err). I would like to find the linear regression
coefficients A and B (in y=Ax+B) considering the errors in my data
point. Is their a function in IDL which would do the trick? and the
regression has to do with the errors in y only but not in x, right?

Thank you for your help.
