Density ratio model for multiple types of survival data with empirical likelihood
James Hugh McVittie, Archer Gong Zhang
The density ratio model (DRM) is a semiparametric model that relates the distributions from multiple samples to a nonparametrically defined reference distribution via exponential t…
Sample Size Determination Under Selection Bias: Robust Tolerance Limits for Prevalent Cohort Data
James H. McVittie, Martin Lysy, Masoud Asgharian
Tolerance limits have received considerable attention in the statistical literature, with applications reaching far beyond their initial role in quality control. The well-known for…
Weighted Parameter Estimators of the Generalized Extreme Value Distribution in the Presence of Missing Observations
James H. McVittie, Orla A. Murphy
Missing data occur in a variety of applications of extreme value analysis. In the block maxima approach to an extreme value analysis, missingness is often handled by either ignorin…
Estimating Extreme Wave Surges in the Presence of Missing Data
James H. McVittie, Orla A. Murphy
The block maxima approach, which consists of dividing a series of observations into equal sized blocks to extract the block maxima, is commonly used for identifying and modelling e…
