An observation‐driven state‐space model for claims size modelling

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract State‐space models are popular in econometrics. Recently, these models have gained some popularity in the actuarial literature. The best known state‐space models are of the Kalman‐filter type. These are called parameter‐driven because the observations do not impact the state‐space dynamics.

On subset least squares estimation and prediction in vector autoregressive models with exogenous variables

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract We establish the consistency and the asymptotic distribution of the least squares estimators of the coefficients of a subset vector autoregressive process with exogenous variables (VARX). Using a martingale central limit theorem, we derive the asymptotic normal distribution of the estimators. Diagnostic checking is discussed using kernel‐based

Addressing Causality and Homogeneity Assumptions in Exposure‐Response Analyses

open access: yesClinical Pharmacology &Therapeutics, EarlyView.
Exposure‐response, or pharmacokinetic–pharmacodynamic (PKPD), analyses support many drug development decisions. It is typically applied without assessment of causality and homogeneity, where the latter refers to the assumption that the reason for variability in exposure is unimportant for the impact on response.
