Investigates error analysis using weighted sums to infer results from observations.
Summary For normal observations {Xi, j = 1, …, N}, certain weighted sums Yi, are used to draw inferences about the sum Y of a further N observations. The same family of weights {Wij} are applied in error analysis of general computations t on general samples x1, …, xN, with approximate validity in a wide range of situations.
