Hi @raphaelvallat,

could you please add a center parameter to the homoscedasticity() function?

homoscedasticity() uses the median which is in fact the Brown-Forsythe version, but the normal levene test uses the mean as far as I know.

Thank you very much!

Best regards!

Hi @rnesti,

Pingouin is based on the scipy.stats.levene function, which uses the median by default. I'll add the center parameter in the next release of Pingouin 👍

Thanks,
Raphael
