This near-zero matrix is now singular for some maximum lag number (>=5) and thus the test crashes.

The text was updated successfully, but these errors were encountered: Copy link Contributor fscottfoti commented Jun 2 I think that clears it up -- your fixed effects are perfectly collinear (that is why the smallest singular value is 10^-14). Your design matrix has 6 columns (that is why you are getting 6 singular values, or you can just check md.exog.shape).

General purpose Hi Team, 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: Build logistic regression model (using statsmodels package/library) import statsmodels.api as sm M1 = sm.Logit(Train_Y, Train_X) # (Dep_Var, Indep_Vars) # This is model definition M1_Model = M1.fit So I tried to solve the matrix above but I couldn't.

2021-01-26 · The inverse of a matrix is a reciprocal of a matrix. 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.
