What does the 'bse' in the `results` object represent?

In `statsmodels`, `results.bse` is a list containing the standard errors for each coefficient in the regression model. The index of the list corresponds to the coefficient (e.g., the first element represents the intercept, the second the slope of x, etc.). Therefore, `results.bse[1]` gives you the standard error of the slope coefficient for the 'x' variable.
