Admissibility of the usual confidence interval in linear regression. (English) Zbl 1329.62049

Summary: Consider a linear regression model with independent and identically normally distributed random errors. Suppose that the parameter of interest is a specified linear combination of the regression parameters. We prove that the usual confidence interval for this parameter is admissible within a broad class of confidence intervals.
