Report

On the maximum likelihood degree of linear mixed models with two variance components

Autor: Grzadziel, Mariusz

We extend the results concerning the upper bounds for the maximum likelihood degree and the REML degree of the one-way random effects model presented in Gross et al. [Electron. J. Stat. 6 (2012), pp. 993-1016] to the case of the normal linear mixed m

Report

A note on the existence of the maximum likelihood estimate in variance components models

Autor: Grządziel, Mariusz, Michalski, Andrzej

In the paper, the problem of the existence of the maximum likelihood estimate and the REML estimate in the variance components model is considered. Errors in the proof of Theorem 3.1 in the article of Demidenko and Massam (Sankhy\=a 61, 1999), giving

On using nonparametric approaches for precipitation estimation

Autor: Grządziel Mariusz

Publikováno v: ITM Web of Conferences, Vol 23, p 00013 (2018)

Nonparametric density estimation methods have been used for precipitation estimation for decades. The new approach for estimating the density proposed recently by Geenens and Wang appears to offer advantages over them as far as their behavior in the
