Can't find all levels of categorical predictors in output of zeroinfl()
...ing zeroinfl() under the pcsl library as an
alternative to factorial ANOVA (I?ve also tried the zero-inflated negative
binomial). This is early in my data-analysis, but I will likely incorporate
additional categorical and continuous predictors at a later time.
This gives me the following model:
zipclay=zeroinfl(AVInt ~ Elev + Treatment)
So running the model, I have:
> zipclay=zeroinfl(AVInt ~ Elev + Treatment)
> summary(zipclay)
Call:
zeroinfl(formula = AVInt ~ Elev + Treatment)
