Measurement Techniques Aims and scope

Abstract

The distribution of residuals in one series of measurements is obtained. It is shown that the normally used t interval for residuals is always wider than the correct one. The question of the detection of gross errors in the graphs of residuals is discussed. Reliable detection of gross errors is possible only for extremely small ratios of the number of parameters of the model to the number of nodes (≤0.1).
