WebbThe resulting fitted equation from Minitab for this model is: Progeny = 0.12796 + 0.2048 Parent. Compare this with the fitted equation for the ordinary least squares model: Progeny = 0.12703 + 0.2100 Parent. The equations aren't very different but we can gain some intuition into the effects of using weighted least squares by looking at a ...
