Weighted percentile using numpy

Question

Is there a way to use the numpy.percentile function to compute weighted percentile? Or is anyone aware of an alternative python function to compute weighted percentile?

Answer 1

I don' know what's Weighted percentile means, but from @Joan Smith's answer, It seems that you just need to repeat every element in ar, you can use numpy.repeat():

import numpy as np
np.repeat([1,2,3], [4,5,6])

the result is:

array([1, 1, 1, 1, 2, 2, 2, 2, 2, 3, 3, 3, 3, 3, 3])
