Rank-Based Family of Probability Laws for Testing Homogeneity of Variable Grouping

Mathematics
In order to test within-group homogeneity for numerical or ordinal variable groupings, we have introduced a family of discrete probability distributions, related to the Gini mean difference, that we now study in a deeper way. A member of such a family is

Cumulant-Based Goodness-of-Fit Tests for the Tweedie, Bar-Lev and Enis Class of Distributions

Mathematics, 2023
The class of natural exponential families (NEFs) of distributions having power variance functions (NEF-PVFs) is huge (uncountable), with enormous applications in various fields.

Asymptotics for the Moments of Singular Distributions

Journal of Approximation Theory, 1993
The authors determine the asymptotic behavior of the moments of some singular distributions defined on \([0,1]\), including the Cantor singular function and some special cases of the Riesz-Nagy singular function. The authors also present some numerical studies of the coefficients in the recurrence relation for the orthogonal polynomials generated by ...

Maximum-likelihood estimation of the Po-MDDRCINAR(p) model with analysis of a COVID-19 data

Statistical Theory and Related Fields
Integer-valued data are frequently encountered in time series studies. A pth-order mixed dependence-driven random coefficient integer-valued autoregressive time series model (Po-MDDRCINAR(p)) in view of binomial and negative binomial operators, where the

Inference for the Linear IV Model Ridge Estimator Using Training and Test Samples

Stats, 2021
The asymptotic distribution is presented for the linear instrumental variables model estimated with a ridge penalty and a prior where the tuning parameter is selected with a holdout sample. The structural parameters and the tuning parameter are estimated

On the Convergence Rate for the Longest at Most T-Contaminated Runs of Heads

Entropy
In this paper, we study the usual coin tossing experiment. We call a run at most T-contaminated, if it contains at most T tails. We approximate the distribution of the length of the longest at most T-contaminated runs.
