Dear all,
I am
fitting a hurdle model in the following way:
HNB <-
hurdle(chro ~ as.factor(TandemRepeat)| as.factor(TandemRepeat), data
=data_negbin_fin,
dist = "negbin")
But the std.
error for log(theta) = NA
Count model
coefficients (truncated negbin with log link):
Estimate Std. Error z value
Pr(>|z|)
Log(theta) 13.5062 NA NA NA
And it
gives the following error:
In
sqrt(diag(vc_count)[kx + 1]) : NaNs
Can
somebody help me please.
Thanks so
much
Ana
