Hello!

Does anybody know a way to weight the line of best fit towards points on a scatterplot that are 'more important' than others? So, if I'm looking for the 'y = mx+b' formula at the end of the day, I'd like it to, for example, still take 50 out of the 100 points on the scatterplot into account -- but skew the line/formula more heavily towards the other 50 points that I designated with a heavier weight.

Is that possible?

Thanks!
