the observed "log odds" in logistic regression
...,
do I still have to generate such a table and compute the log odds for each
level of IV according to which the log odds are calculated?
In R , fitted(fit) gives the fitted probability for DV to be 1. Dose the
observed probability exist ? If it does exist , how can I extract it ? If
the IV is cartegorical , the DV can readily changed to be a tow-culumned
matrix, thus log(the observed probabily/(1-the observed probability) might
be the "log odds". I wonder what if the IV is continuous ?
And about the residuals. It seems that the residual is not the actual
DV minus the fitted probabili...
