Calculate a p-value in Python

Question

I used the statsmodels.formula.api as below to calculate P-values. But apparently, this is not working in the new versions of the library. Do you know an alternative tool?

import statsmodels.formula.api as sm
# ...
regressor_OLS = sm.OLS(Y, x).fit()

Error:

AttributeError: module 'statsmodels.formula.api' has no attribute 'OLS'

Answer 1

Use statsmodels.api , instead of statsmodels.formula.api .

Answer 2

try changing
regressor_OLS = sm.OLS(Y, x).fit()
to
regressor_OLS = sm.OLS(endog=Y, exog=x).fit()
