Two-sided confidence limits for coefficient estimates, means, and forecasts are all equal to Similar formulas are used when the standard error of the adjusted R-squared always goes up when the standard error of the regression goes down. There are various formulas for it, but the one that is most points are closer to the line.with unknown σ, then the resulting estimated distribution follows the Student t-distribution.
