Robust Estimation of the Generalized Loggamma Model. The R Package robustloggamma [PDF]

, 2015
robustloggamma is an R package for robust estimation and inference in the generalized loggamma model. We briefly introduce the model, the estimation procedures and the computational algorithms.

A General Class of Confidence Interval [PDF]

Nature, 1946
AMONG types of statistical inference about unknown parameters statements are possible which have a statistical truth, that is, they are random variables such that within the statistical framework adopted the probability of their being in error is known.

Determinants of anemia and hemoglobin concentration in haitian school-aged children [PDF]

, 2015
Anemia diminishes oxygen transport in the body, resulting in potentially irreversible growth and developmental consequences for children. Limited evidence for determinants of anemia exists for school-aged children.

Assessing Performance of the Generalized Exponential Model in the Presence of the Interval Censored Data with Covariate

Austrian Journal of Statistics, 2022
This study aims to extend the generalized exponential model (GEM) to include covariates in the presence of interval-censored data. The maximum likelihood estimator (MLE) was obtained for the parameter of the model formulated.

Simultaneous Confidence Intervals for Pairwise Differences of Means in Zero-Inflated Rayleigh Distributions with an Application to Road Accident Fatalities Data

Mathematics
This paper develops simultaneous confidence intervals (SCIs) for pairwise differences of means with zero-inflated Rayleigh (ZIR) distributions, a flexible framework for modeling positively skewed data with excess zeros.
