Numpy rank correlation
Web8 mrt. 2024 · 首先，我们需要导入NumPy库，因为它提供了计算相关系数的函数。 2. 接下来，我们定义了两个向量x和y。这里使用NumPy库的array函数将列表转换为向量。 3. 然后，我们使用NumPy库的corrcoef函数计算x和y的相关系数。 WebThe correlation coefficient matrix R is computed using the covariance matrix C as given by R_ {ij} = \frac { C_ {ij} } { \sqrt { C_ {ii} * C_ {jj} } } Rij = Cii∗CjjCij Note Due to floating point rounding, the resulting array may not be Hermitian and its diagonal elements may not be 1.
