correlation coefficient python code example

Example 1: correlation coefficient python numpy example

>>> r = np.corrcoef(x, y)
>>> r
array([[1.        , 0.75864029],
       [0.75864029, 1.        ]])
>>> r[0, 1]
0.7586402890911867
>>> r[1, 0]
0.7586402890911869

Example 2: python pearson correlation

import scipy
# x and y are numpy array with shape (N,)
coeff, _ = scipy.stats.pearsonr(x, y)
