Subject: CORRECTION: Re: Multicollinearity with brglm?
In-Reply-To: <22814696.post@talk.nabble.com>
I'm running brglm to do binomial loguistic regression.
The perhaps multicollinearity-related feature(s) are:
(1) the k IVs are all binary categorical, coded as 0 or 1;
(2) each row of the IVs contains exactly C (< k) 1's; (I think this is the
source of the problem)
(3) there are n * k unique rows, where n is as much as 10;
(4) when brglm is run, at least 1 IV is reported as involving a singularity
and this occurs for nearly every choice of k, n.
How should I go about computing estimates for the offending IVs? I'm
interested primarily in the reliability of the parameter estimates.
