Over the years, my colleagues and I have come to realise that the likelihood of
pharmaceutical drugs being able to diffuse through whatever unhindered phospholipid …

We propose three new estimators of the Weibull distribution parameters which lead to three
new plug-in estimators of quantiles. One of them is a modification of the maximum likelihood …

We obtain a simple non-parametric estimator of the Gini index when the sample contains
right censored observations. Asymptotic properties of the proposed estimator are studied …

The Gini index is a popular inequality measure with many applications in social and
economic studies. This paper studies semi-parametric inference on the Gini indices of two …

Originally proposed to measure income or wealth inequality (Gini, 1912, 1914), the Gini
concentration index has become one of the most common statistical indices employed for …

This study considers discrete choice models with a censored covariate under dependent
censoring where the censoring mechanism depends on the outcomes of choice models. We …

Function-based hypothesis testing in two-sample location-scale models has been
addressed for uncensored data using the empirical characteristic function. A test of …

Measuring the difference between two Gini indexes is important in comparing the inequality
between two groups. This paper systematically provides confidence intervals for this …

The semiparametric density ratio model (DRM) provides a flexible and useful platform for
combining information from multiple sources. It has been widely used in many fields. This …

Estimators of the Gini index have been proposed and widely utilized for interval estimation
and hypothesis testing in economics. In this paper, Jackknife Empirical Likelihood (JEL) is …
