include_reference doesn't work for pscl models #1130
Description
Hello,
the include_reference parameter doesn't seem to work for pscl model.
Here it is in action for a lm model:
> mydf <- pscl::bioChemists
> model <- lm(art ~ fem + mar, data = mydf)
> parameters::model_parameters(model, include_reference=TRUE)
Parameter | Coefficient | SE | 95% CI | t(912) | p
---------------------------------------------------------------------
(Intercept) | 1.85 | 0.14 | [ 1.58, 2.12] | 13.46 | < .001
fem [Men] | 0.00 | | | |
fem [Women] | -0.40 | 0.13 | [-0.66, -0.14] | -3.06 | 0.002
mar [Single] | 0.00 | | | |
mar [Married] | 0.05 | 0.14 | [-0.23, 0.32] | 0.34 | 0.737
and here it is for a pscl model:
> model <- pscl::zeroinfl(art ~ fem + mar, data = mydf)
> parameters::model_parameters(model, include_reference=TRUE)
