The matrix you pasted: [[ 1, 8, 50], [ 8, 64, 400], [ 50, 400, 2500]] Has a determinant of zero. This is the definition of a Singular matrix (one for which an inverse does not exist)
The problem arises due to the perfect correlation between the two series in your data. From the traceback, you can see, that internally a wald
I am trying to build and run a logistic regression model (with a very large dataset). After data cleaning, dummy creation and vif check when tried to run the model i am getting below error: numpy.linalg.LinAlgError: singular matrix . Solutions. Linear error: singular matrix. It can be seen that the current matrix is irreversible, Solution. Modify the current matrix, not a 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.

It is also defined as a matrix formed which, when multiplied with the original matrix, gives an identity matrix. A matrix’s inverse occurs only if it is a non-singular matrix, i.e., the determinant of a matrix should be 0.
