abstract = "A general formula is presented for the variance of the sum of predictions from a weighted linear regression equation. This is an extension of O'Regan's (1964) work. Simple formulas are given for the univariate regression case; the regression has a nonzero intercept, and the independent variable may be compound. An example is presented illustrating equation use.
