OOBPredictorImportance How to interpret the values range?

5 visualizzazioni (ultimi 30 giorni)
To be able to calculate the importance of the predictors for TreeBagger it is needed to turn on the OOBPredictorImportance parameter
Mdl = TreeBagger(200,X,'MPG','Method','regression','Surrogate','on','PredictorSelection','curvature','OOBPredictorImportance','on');
I would like to know what is the range of the parameters, the results for my regression is beetween 0 and 1.5, is that good? bad? What more conclusions can I draw from that vector?
Thanks for your time!

Hi, really this parameter have no range. This parameter only explain you how important is a band compared to other bands. When you a have a higuest values associated with a band, this indicates that this band is more important than the rest.
You can make the result more visual by applying the bar () function on the OOB vector to make a bar diagram.

Ok, thanks for you input.
I tought that perhaps it would be on percentage or something like that. IT is more quanlitative then quantitative.
