In some acquired immunodeficiency syndrome (AIDS) clinical trials, the human
immunodeficiency virus-1 ribonucleic acid measurements are collected irregularly over time …

Larkspur (Delphinium spp.) poisoning is a long-term problem for cattle grazing on
rangelands of western North America. Results from preliminary experiments have suggested …

Linear mixed-effects models are commonly used when multiple correlated measurements
are made for each unit of interest. Some inherent features of these data can make the …

Longitudinal HIV-1 RNA viral load measures are often subject to censoring due to upper and
lower detection limits depending on the quantification assays. A complication arises when …

This paper proposes some diagnostics procedures for the skew-t linear regression model
with censored response. The skew-t distribution is an attractive family of asymmetrical heavy …

This research will explore the modified outlier diagnostics for the exponentiated exponential
regression (EER) model with interval and right-censored data using adjusted residuals and …

In many studies, limited or censored data are collected. This occurs, in several practical
situations, for reasons such as limitations of measuring instruments or due to experimental …

The purpose of this paper is to develop a practical framework for the analysis of the linear
mixed-effects models for censored or missing data with serial correlation errors, using the …

Mixed-effects models, with modifications to accommodate censored observations
(LMEC/NLMEC), are routinely used to analyze measurements, collected irregularly over …

In many applications, statistical models for real data often have natural constraints or
restrictions on some model parameters. For example, the growth rate of a child is expected …
