how to identify a fitglm output as being rank deficient from the resulting object

3 visualizaciones (últimos 30 días)
My question is as follows:
I am running a very large number of multivariable regressions. My problem is that sometimes these are identified as being rank deficient regressions. I am totally cool with that, but I would like to be able to identify them as so once my loop is complete.
Is there a way to identify if a regression is rank deficient from the object that fitglm outputs?

If your model is f, you could see if
f.NumCoefficients > f.NumEstimatedCoefficients
