Zero-Inflated Generalized Linear Mixed Models: A Better Way to Understand Data Relationships

open access: yesMathematics, 2021
Our article explores an underused mathematical analytical methodology in the social sciences. In addition to describing the method and its advantages, we extend a previously reported application of mixed models in a well-known database about corruption ...

Multilevel ensemble Kalman filtering for spatio-temporal processes

open access: yes, 2020
We design and analyse the performance of a multilevel ensemble Kalman filter method (MLEnKF) for filtering settings where the underlying state-space model is an infinite-dimensional spatio-temporal process.
