Without the intercept, the standard errors seem to vary with n of each level, i.e. It should give the standard error you mention.

In the first model, the effect of religionChristianity is a variation in the outcome wrt the baseline (religionBuddhism), a relative variation. pred <- predict(y.glm, newdata= something, se.fit=TRUE) If you could provide online source (preferably on a university website), that would be fantastic. Is there an adverb meaning "by volunteering"? R Regression Standard Error Linked 0 How to calculate R logistic regression standard error values manually?
An important effect of the separation is to make the standard errors very large, which essentially makes the Wald tests worthless. The coefficients are asymptotically normal so a linear combination of those coefficients will be asymptotically normal as well. The diagonal of this matrix contains the variances of the coefficients, and the standard errors are simply the square root of these variances. Error t value Pr(>|t|) (Intercept) 10.2758 0.5185 19.817 < 2e-16 *** rprice2 -1.8581 0.5139 -3.616 0.000696 *** I would like to use the Std.
