Description: In the article the two methods of the determination of the location μ and width σ parameters of the input uncorrelated observations as a result of comparison of the input sorted observations with the set of the so-called reference observations are proposed and investigated. The elements of reference samples are the expectations of random position statistics corresponded to general population density distribution of observations. The measurement result according to the first method is based on the determination of the minimum value of residual sums of squares deviations of input from the all set reference observations. In the second method result is calculated as the weighted mean from all results, in this case the weight coefficients are proportional to the inverse values of appropriate residual sums of squares deviations. The efficiency of these models is investigated by the Monte Carlo method.
