Hi all,
Me again...I couldn't find how to plot or check the residuals in my linear regression.
Should I create a new column comparing actual values and predictions?
And how about errors in a regression?
Tks again
Fabio,
I do a lot of Regressions and yes - for all I can tell residuals are best computed by hand. I've also built a flow to give me Cook's distances of the residuals, etc.
The "Numeric Scorer" node will give you the overall model error stats.
Cheers
E
