...tion. Currently, I'm working on a project in which there are observations collected in many cities, represented by a variable PLACE. We are comparing the effect of several variables on a response for each of the values of a RACE variable. RACE is dichotomized into "White" and "Nonwhite" by the people who collect the data. For Nonwhites only, we can estimate the effect of individual level predictors (x) on the output (y). fm1 <- lmer( y ~ x + (1 | PLACE), data=dat, , family=binomial, subset= Race %in% c("Nonwhite")) The random effect in this model indicates t...

Dear users, In my psychometric test i have applied logistic regression on my data. My data consists of 50 predictors (22 continuous and 28 categorical) plus a binary response. Using glm(), stepAIC() i didn't get satisfactory result as misclassification rate is too high. I think categorical variables are responsible for this debacle. Some of them have more than 6 level (one has 10 level).
