WebbIn this case, pca computes the (i,j) element of the covariance matrix using the rows with no NaN values in the columns i or j of X.Note that the resulting covariance matrix might not be positive definite. This option applies when the algorithm pca uses is eigenvalue decomposition. When you don’t specify the algorithm, as in this example, pca sets it to 'eig'.
