Regression Coefficient Confidence Interval Calculator

This calculator will compute the 99%, 95%, and 90% confidence intervals for a regression coefficient, given the value of the regression coefficient, the standard error of the regression coefficient, 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 coefficient (β):	The value of the regression coefficient associated with a specific independent variable in the linear model.
Sample size:	The total number of valid cases used in the analysis.
Standard error (SE_β):	The standard error associated with the regression coefficient.
