WebSep 1, 2024 · To get a general formula for a multiple regression coefficient standard error, you need to use linear (matrix) algebra. The formula for the variance-covariance matrix of the betas is: V C O V ( β ^) = s 2 ( X ′ X) − 1 From there, you take the positive square root of the j t h diagonal element to get the standard error of that beta.
