recommendations! Published in 2017 at "Environmetrics"

DOI: 10.1002/env.2464

Abstract: Environmental data are often spatially correlated and sometimes include observations below or above detection limits (i.e., censored values reported as less or more than a level of detection). Existing research studies mainly concentrate on parameter… read more here.

DOI: 10.1002/sim.7584

Abstract: Missing covariate values are prevalent in regression applications. While an array of methods have been developed for estimating parameters in regression models with missing covariate data for a variety of response types, minimal focus has… read more here.

DOI: 10.1080/02664763.2016.1182128

Abstract: ABSTRACT Since the seminal paper by Cook and Weisberg [9], local influence, next to case deletion, has gained popularity as a tool to detect influential subjects and measurements for a variety of statistical models. For… read more here.

recommendations! Published in 2017 at "Statistical Methods in Medical Research"

DOI: 10.1177/0962280215615597

Abstract: This paper aims to develop diagnostic measures to assess the influence of data perturbations on estimates in AB-BA crossover studies with a Poisson distributed response. Generalised mixed linear models with normally distributed random effects are… read more here.
