Re: [R] model II regression - how do I do it?

Why Model II Regression? My experience is that for purposes of prediction, the difference between Model I and Model II fits can be quite significant, mostly, of course, near the extremes of the predictor variable(s). There are several approaches and most give pretty similar model parameters but mo

[R] Incorrect p value for binom.test?
