Dear Mr. or Ms.,

I used the R-software to run the zero-inflatoin negative binomial model, but I could not get the results. And the error message is "solve.default(as.matrix(fit$gaussian)) ". In the model, I introduced 3 dummy variables. I do not know the reasons fully.

I will be very appreciate if you can help me. Thank you.

Best regards,

Xiongqing Zhang
