Question #3a Issue - LinAlgError: Singular Matrix

[TomPCurran]

I am trying to run the logit regresison using sm.Logit(), but keep getting the error:

LinAlgError: Singular matrix when I try to use the .fit() method on the model:

exog = ['constant','cylinders','displacement','horsepower','weight','year', 'origin']

logit = sm.Logit(endog = df_quant2['mpg_high'], exog = df_quant2[['constant','cylinders','displacement','horsepower','weight','year', 'origin']])

any suggestions?
