Weighted regression line on scatter plot

Hi,

I'm trying to plot a weighted regression line on my scatter plot. The command

lsline

only seems to give me a non-weighted regression line. Given a vector y, a vector X and a weighting vector w is there a quick command to draw a weighted regression line?

Thanks!
