Regression Intercept Confidence Interval Calculator

This calculator will compute the 99%, 95%, and 90% confidence intervals for a regression intercept (i.e., the regression constant), given the value of the regression intercept, the standard error of the regression intercept, the number of predictors in the model, and the total sample size.

Please supply the necessary parameter values, and then click 'Calculate'.

Number of predictors:	The total number of predictors in the model, not including the regression constant.
Regression intercept (β₀):	The regression intercept for the linear model. Also known as the regression constant.
Sample size:	The total number of valid cases used in the analysis.
Standard error (SE_β₀):	The standard error associated with the regression intercept.
