Hi,

I'm plotting data with x 2SD vs y 2SD. The error is for most of the data relatively consistent, but for 3 datapoints it is 3-5x larger on x and y (due to lower sensitivity).
I want do a linear fit through the data and take into account the larger errors on x and y. What do I choose for the "Weight" in the fit function?

Thanks
