When I try to solve it in python using np.linalg.solve, I get LinAlgError: Singular matrix. How can I solve this type of equation for singular matrices using python or WolframAlpha? How come several computer programs how problems with this kind of equation? linear …

Analysis finished at Mon Jul 8 09:36:54 2019 Total time elapsed: 34.32s Python sm.logit () - getting LinAlgError: Singular matrix when using model.fit () function. 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.

numpy.linalg.LinAlgError: Matrix is singular.. In X and coord are numbers (positive and few negative ones, coord are coordinates longitude and latitude). The Model im trying to use is from this Library: from mgwr.gwr import GWR Docs found here. Prediction is here. Any help would greatly be appreciated!

Hi Santiago, This message is letting you know that your independent variables are correlated, which can result in a matrix that is singular. I recommend that you remove any variable that seems like it would be perfectly correlated with any of the other variables and try your logistic regression again.
