ERROR: UndefVarError: l not defined
Stacktrace:

According to the docs (https://juliastats.org/StatsBase.jl/stable/transformations/#StatsBase.fit-Tuple{Type{ZScoreTransform},AbstractArray{#s4,2}%20where%20#s4%3C:Real}),

The default is nothing, which is equivalent to dims=2 with a deprecation warning.

so either the docs need updating or dims should be made a required keyword argument.
