The paper is devoted to the study of long-term variability of the stable dates of ice formation and the duration of the freeze-up period at 12 gauges on the rivers of the Votkinskoe Reservoir catchment for 1936–2018. It turns out which of the stati

A methodological approach is developed to the analysis of long-term series of observations of hydrological characteristics including the testing of the hypothesis of randomness both for the full series and for their parts; the diagnosis of intraserie

An estimator for a distribution quintile is proposed and studied with the use of the unbiased approach within the framework of the exponential distribution family model. The application of the quintile of the distribution function’s unbiased estima

We propose two new variants of chi-square-type statistics for testing the hypothesis on the shape of a distribution belonging to the one-parameter exponential family. Each variant assumes the use of unbiased estimators of the probabilities for the ra

In this paper on the basis of unbiased estimates the problem of constructing asymptotic confidence interval for P(X < Y) is solved for the case where random variables X and Y have distributions, belonging to one-parameter exponential families.

Long-term variations of ice formation dates are studied using the long (more than 100 years) series of observations of ice regime on the rivers of the Votkinsk Reservoir catchment. Proposed is the methodological approach to assessing the long-term va

Unbiased estimates have been successfully used in the solution of different tasks for a rather long time. At present, there are works containing tables of unbiased estimates of parameters and functions from many probability distributions (see, for ex
