Support for a categoricalArray as the dependent variable for GLM models

Currently a categorical array on the left hand side in a GLM model generates an error message: ``` MethodError: no method matching zero(::Type{CategoricalArrays.CategoricalValue{Int8,UInt32}}) Closest candidates are: zero(::Type{Base.LibGit2.GitHash}) at libgit2\oid.jl:106 zero(::Type{Base.Pkg.Resolve.VersionWeights.VWPreBuildItem})...

nulldeviance function

It is not currently defined in GLM. Can this be added? It is required for pseudo R2 for GLM models. I think this works: ``` function StatsBase.nulldeviance(obj::GeneralizedLinearModel) return deviance( glm(@formula(y...

The following code explains the problem: using DataFrames, CategoricalArrays, FreqTables df = DataFrame(id = 1:9, race = repeat(collect(1:3),3)) df.race = categorical(df.race) freqtable(df,:race) 3-element Named Vector{Int64} race │ ──────┼── 1 │...
