There are multiple tests of homogeneity of binomial proportions in the statistics literature. However,
when working with sparse data, most test procedures may fail to perform well. In this article we review
nine classical and recent testing procedures, including the standard Pearson and likelihood...

The log-logistic distribution (also known as the Fisk distribution in economics) is widely used in survival
analysis when the failure rate function presents a unimodal shape. In this paper, we introduce the Zografos-
Balakrishnan log-logistic distribution, which contains the log-logistic distribution...

A semi-Markov process with four states, has been applied for modeling two dissimilar unit cold standby systems. At the moment that operating unit fails, the standby unit is switched to operate by using a switching device that is available with unknown probability alpha1. It is also assumed that the failure...

We consider six different estimators of residual heterogeneity in random-effects meta-regression, five estimators already known and implemented in the R package metaphor and one estimator not yet considered
in random-effects meta-regression. In a numerical study, we investigate the properties of these...

In this paper, we discuss the optimal accelerated life test plans for Burr type X distribution with log-linear model under
periodic inspection and Type I censoring. We obtain the maximum likelihood estimators, the Fisher information and
the asymptotic covariance matrix of the maximum likelihood estimators....

The paper considers a linear regression model in high-dimension for which the predictive variables can
change the influence on the response variable at unknown times (called change-points). Moreover, the
particular case of the heavy-tailed errors is considered. In this case, least square method with...

In this paper, we derive explicit expressions for Bonferroni Curve (BC), Bonferroni index (BI), Lorenz Curve (LC) and Gini index (GI) for the Marshall-Olikn Exponential (MOE) distribution, which have mainly concern
with some aspects like poverty, welfare, decomposability, reliability, sampling and inference.We...
