Dear R-helpers, I am very new to R and trying to run the conditional logit model using "clogit " command. I have more than 4000 observations in my dataset and try to predict the dependent variable from 14 independent variables. My command is as follows
clmtest1 <- clogit(Pin~Income+Bus+Pop+Urbpro+Health+Student+Grad+NE+NW+NCC+SCC+CH+SE+MRD+strata(IDD),data=clmdata) However, it produces the following errors: Error in fitter(X, Y, strats, offset, init, control, weights = weights, : NA/NaN/Inf in foreign function call (arg 6) In addition: Warning messages: 1: In Surv(rep(1, 4096L), Pinmig) : Invalid status value, converted to NA 2: In fitter(X, Y, strats, offset, init, control, weights = weights, : Ran out of iterations and did not converge I search the error message from R forums but it does not say anything for Conditional Logit Model. Please check for me what it says and what should I do to solve it. Thanks a lot for your help Hien Nguyen ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
