What does this implement/fix?
Adds axis / nan_policy / keepdims support to
scipy.stats.levene
andscipy.stats.fligner
.Additional information
@tirthasheshpatel Based on our discussion about the trimmed statistics, I'm assuming it's ok if
proportiontocut
only supports scalars?fligner
had special handling for size-0 arrays, so I updated it to return NaN of the correct dtype.levene
did not - it just pops out of the calculation. But the calculation never respects dtype, including when the array is of size-0. I don't see a need to fix that at this time.
