Censored autoregressive regression models with Student‐t innovations

Canadian Journal of Statistics, Volume 52, Issue 3, Page 804-828, September 2024.
Abstract Data collected over time are common in applications and may contain censored or missing observations, making it difficult to use standard statistical procedures. This article proposes an algorithm to estimate the parameters of a censored linear regression model with errors serially correlated and innovations following a Student‐t distribution.

Rocky outcrops form islands of high and unique tree biodiversity within an ocean of grass in Serengeti National Park

African Journal of Ecology, Volume 62, Issue 3, September 2024.
Abstract African savannahs are characterised by a high plant diversity, partly resulting from a high turnover in community compositions across space. However, it is poorly understood what is driving this spatial turnover in plant communities. Here, we investigate to which extent the presence of rocky outcrops (also called kopjes) explains the community

Comparison of the AquaCrop and CERES‐Maize models for simulating maize phenology, grain yield, evapotranspiration and water productivity under different irrigation and nitrogen levels

Irrigation and Drainage, Volume 73, Issue 3, Page 1052-1068, July 2024.
Abstract The CERES‐Maize and AquaCrop models were evaluated for their performance in simulating maize (Zea mays L.) phenology, evapotranspiration (ETc), grain yield and crop water productivity (CWP). Model input data for calibration, validation and simulations were obtained from field experiments conducted from 2011 to 2014 that imposed three different
