Chi-square goodness-of-fit test for one- and multidimensional discrete distributions

Autor: V. G. Voinov, M. S. Nikulin

Publikováno v: Journal of Mathematical Sciences. 68:438-450

The problem of the construction of chi-square type tests for discrete (one- and multidimensional) distributions of exponential type is considered in detail. In particular, as an example, the Stirling distribution of the second kind is investigated a

[Statistical models of longevity, aging and degradation in demography, gerontology and oncology]

Autor: M S, Nikulin, V N, Anisimov, A M, Nikulin

Publikováno v: Advances in gerontology = Uspekhi gerontologii. 24(3)

Several interesting papers related with the problems of mathematical modelling in connection with a study of aging and longevity have been published recently in "Advances of Gerontology"; see, for example, [1-4, 10, 11]. Following the main idea of th

Flexible regression models for dynamic prediction of survival in elderly in presence of cancer or other chronic diseases

Autor: A J, Sasco, M S, Nikulin

Publikováno v: Advances in gerontology = Uspekhi gerontologii. 21(1)

We consider degradation and failure time models with multiple failure modes adapted for the statistical analysis of survival in the elderly in presence of chronic diseases such as cancer, but also other conditions like dementia, Alzheimer, diabetes,

Estimation of the efficiency of Bol'shev's decision rule in the problem of the distinguishing of two hypotheses

Autor: M. S. Nikulin

Publikováno v: Journal of Soviet Mathematics. 52:2955-2964

In this communication the efficiency of Bol'shev's optimal decision rule is discussed. The possibility of the use of this rule is considered in the problem of the distinguishing of composite hypotheses in the presence of sufficient statistics.

Estimation in degradation models with explanatory variables

Autor: V, Bagdonavicius, M S, Nikulin

Publikováno v: Lifetime data analysis. 7(1)

Influence of covariates on degradation is modelled. Models which include dependence of the intensity of the process of traumatic events on the degradation level are also discussed. Estimation of reliability and degradation characteristics from data w

Generalized proportional hazards model based on modified partial likelihood

Autor: V B, Bagdonavicius, M S, Nikulin

Publikováno v: Lifetime data analysis. 5(4)

The proportional hazards (Cox) model is generalized by assuming that at any moment the ratio of hazard rates is depending not only on values of covariates but also on resources used until this moment. Relations with generalized multiplicative, frailt

Model Building in Accelerated Experiments

Autor: M. S. Nikulin, V. Bagdonavičius

Publikováno v: Statistical and Probabilistic Models in Reliability ISBN: 9781461272809

A review of main known and new models used in accelerated life testing is done. An unifying approach of model formulation is used. Only models for which estimation procedures are known are considered.

Autor: V. Bagdonavičius, M. S. Nikulin

Publikováno v: Statistical and Probabilistic Models in Reliability ISBN: 9781461272809

Additive accumulation of damages model and its generalizations are considered. Semiparametric estimation procedure of the survival function under the normal stress from accelerated life testing data is proposed. Experiments with step-stresses with ra
