DOI: 10.1007/s11203-018-9182-z
Abstract: In this article, a time series analysis of covariance model is introduced when covariates time series have lead–lag relationship with response time series. Parameter estimation and hypothesis testing for this model are made in spectral… read more here.

Abstract: This article discusses the robustness of the multivariate analysis of covariance (MANCOVA) test for an emergent variable system and proposes a modification of this test to obtain adequate information from heterogeneous normal observations. The proposed… read more here.

DOI: 10.1080/03610926.2025.2500639
Abstract: Abstract. There are two approaches to non-parametric pairwise comparisons of treatment effects: the method based on pairwise rankings and the method based on overall ranking. The former is generally recommended in the literature because of… read more here.

Abstract: T he analysis of covariance (ANCOVA) was developed over 85 years ago by Ronald Fisher, arguably the father of modern statistics. Since that time, it has occupied a seemingly paradoxical position: vastly under-used in situations… read more here.

DOI: 10.1111/biom.13062
Abstract: "Covariate adjustment" in the randomized trial context refers to an estimator of the average treatment effect that adjusts for chance imbalances between study arms in baseline variables (called "covariates"). The baseline variables could include, for… read more here.

DOI: 10.1155/jom/1131677
Abstract: This paper proposes a model for analysis of covariance (ANCOVA) of censored data obtained from a positively skewed population by using the mixed inverse Gaussian (MIG) distribution. A hierarchical fully Bayesian approach is employed to… read more here.

DOI: 10.4097/kja.24820
Abstract: Analysis of covariance (ANCOVA) is a statistical method used to assess mean differences between groups by considering factors such as covariates or fixed effects and is often used to assess efficacy endpoints in clinical trials.… read more here.
