How Numpy.cov() Function Is Implemented?
I have my own implementation of the covariance function based on the equation: ''' Calculate the covariance coefficient between two variables. ''' import numpy as np X = np.arra
Solution 1:
The numpy function has a different normalization to yours as a default setting. Try instead
>>> np.cov([X, Y], ddof=0)
array([[ 273.88888889, 190.61111111],
[ 190.61111111, 197.88888889]])
