is.glm.nb.theta.error {chicane}

check.glm.nb.theta.error

Description

Check if an error matches the error raised by glm.nb due to an inflated theta estimate. This happens when the variance of the negative binomial does not exceed the mean (i.e. there is no overdispersion). In such cases, the Poisson distribution may be a suitable alternative.
