In weighted least squares, then weights give theoretically correct results for standard errors of. If this looks linear, we could fit a regression.

13.1 – Weighted Least Squares | STAT 501 – The method of ordinary least squares assumes that there is constant variance in the errors (which is called homoscedasticity). The method of weighted least squares can be used when the ordinary least squares assumption of constant variance in the errors is violated (which is called heteroscedasticity).
