What is singular matrix? A square matrix is singular, that is, its determinant is zero, if it contains rows or columns which are proportionally interrelated; in other words, one or more of its rows (columns) is exactly expressible as a linear combination of all or some other its rows (columns), the combination being without a constant term.

This near-zero matrix is now singular for some maximum lag number (>=5) and thus the test crashes. Kzernobog commented on Jul 18, 2018. 'LinAlgError: singular matrix' error pops up when trying to call the pairplot () function. The text was updated successfully, but these errors were encountered: raise LinAlgError("singular matrix") numpy.linalg.LinAlgError: singular matrix #2264 The output window stated the error: numpy.linalg.LinAlgError: singular matrix.

To do this an estimate of the parameters covariance matrix (which is then near-zero) and its inverse is needed (as you can also see in the line invcov = np.linalg.inv (cov_p) in the traceback). This near-zero matrix is now singular for some maximum lag number (>=5) and thus the test crashes.
