sciPy stats.itemfreq() function | Python
scipy.stats.itemfreq(arr, axis = None)
function helps us to calculate the item frequencies.
Parameters :
arr : [array_like] input array.Results : 2D array with item frequency.
Code #1: Use of variation()
# cummulative frequency from scipy import stats import numpy as np arr = [ 14 , 31 , 27 , 27 , 31 , 13 , 14 , 13 ] print ( "Itemfrequency : \n" , stats.itemfreq(arr)) print ( "\n\nBincount : \n" , np.bincount(arr)) |
Output:
Itemfrequency : [[13 2] [14 2] [27 2] [31 2]] Bincount : [0 0 0 0 0 0 0 0 0 0 0 0 0 2 2 0 0 0 0 0 0 0 0 0 0 0 0 2 0 0 0 2]
