WebFeb 27, 2024 · Statsmodels assigns a p -value of 0.109, while Stata returns 0.052 (as does Excel for 2-tailed tests and df of 520). What's going on? Here is the statsmodels docs, which are kind of unhelpful. Below is the output using import statsmodels.formula.api as sm and mod = sm.ols (formula=regression_model, data=data): Webin statsmodels.formula.api, similarly to the R approach, a constant is automatically added to your data and an intercept in fitted in statsmodels.api, you have to add a constant yourself (see the documentation here ). Try using add_constant from statsmodels.api x1 = sm.add_constant (x1) Share Improve this answer Follow answered Jun 4, 2015 at 18:06
