Incorrect Default Coding of Union{Missing, Int or Float64} #145
Description
Pretty straight forward. I would expect the results of these to be the same:
function mwe(N=10)
df = DataFrame(x = rand(N),
zm = Vector{Union{Missing, Int}}(rand(1:4,N)),
z = Vector{Int}(rand(1:4,N)))
println("W/out missings")
f = @eval(@formula(x ~ z))
f = apply_schema(f, schema(f,df), StatisticalModel)
m = modelcols(f.rhs, df)
display(m)
println("With missings")
f = @eval(@formula(x ~ zm))
f = apply_schema(f, schema(f,df), StatisticalModel)
m = modelcols(f.rhs, df)
display(m)
end
mwe()OUTPUT:
