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

Canadian 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

Canadian 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

Stagewise crop yield prediction with multisource functional indices

Canadian Journal of Statistics, EarlyView.
Abstract Index insurance design involves integrating weather data, soil moisture, phenology information, and satellite imagery, which presents challenges in data fusion. This article addresses the modelling of multisource functional indices of varying lengths by constructing a stagewise ensemble of sequential models.

Farmer‐Led Strategies for Water Conservation in the Urmia Lake Basin, Iran

Irrigation and Drainage, EarlyView.
ABSTRACT This study examines the urgent issues of water scarcity and limited farmer livelihoods in the Urmia Lake basin. To address these challenges, we apply the Governance, Autonomy, Integration, and Needs orientation (GAIN) methodology. Our participatory approach revealed that farmers prioritised actionable measures for water management, yield ...

Global determinants of home range sizes in felids: Evidence of human disturbance impact

Journal of Animal Ecology, EarlyView.
This study is the first to demonstrate the influence of anthropogenic factors and species richness in felids on home range size across the entire felid taxon. Felids are a taxon of major interest in conservation biology, and gaining a comprehensive view of their spatial ecology will help derive global conservation recommendations.

Audit Quality From a Service Perspective: A Systematic Literature Review

Accounting Perspectives, EarlyView.
ABSTRACT Audit quality is a multidimensional and latent construct that researchers struggle to evaluate and interpret. This paper follows an interdisciplinary approach by systematically reviewing the literature on audit quality evaluation from a service quality perspective.

Monitoring African Megafauna in an Anthropogenic Landscape: A 15‐Year Case Study of the Vulnerable West African Giraffe

Animal Conservation, EarlyView.
We used pattern recognition software to correct misidentifications in a 15‐year photographic database of the last, vulnerable West African giraffe population in Niger. After revealing substantial methodological errors that had inflated population estimates by nearly 19%, we corrected individual encounter histories and applied capture‐mark‐recapture ...
