Automatic Quality Control for Agricultural Field Trials -- Detection of Nonstationarity in Grid-indexed Data
Karen Wolf, Pierre Fernique, Hans-Peter Piepho
A common assumption in the spatial analysis of agricultural field trials is stationarity. In practice, however, this assumption is often violated due to unaccounted field effects.…
Change of some cropping systems in a long-term trial comparing different systems: rationale and implications for statistical analysis
Hans-Peter Piepho, Ingrid Claß-Mahler, Beate Zimmermann +3
The project Agriculture 4.0 without chemical synthetical plant protection (NOcsPS) tests a number of cropping systems that avoid the use of chemical synthetical pesticides while at…
Regression Models for Order-of-Addition Experiments
Hans-Peter Piepho, Emlyn R. Williams
The purpose of order-of-addition (OofA) experiments is to identify the best order in a sequence of m components in a system or treatment. Such experiments may be analysed by variou…
Hierarchical Bayesian state-space modeling of age- and sex-structured wildlife population dynamics
Sabyasachi Mukhopadhyay, Hans-Peter Piepho, Sourabh Bhattacharya +2
Biodiversity is declining at alarming rates worldwide, including for large wild mammals. It is therefore imperative to develop effective population conservation and recovery strate…
Optimizing the allocation of trials to sub-regions in multi-environment crop variety testing
Maryna Prus, Hans-Peter Piepho
New crop varieties are extensively tested in multi-environment trials in order to obtain a solid empirical basis for recommendations to farmers. When the target population of envir…
A Coefficient of Determination (R2) for Linear Mixed Models
Hans-Peter Piepho
Extensions of linear models are very commonly used in the analysis of biological data. Whereas goodness of fit measures such as the coefficient of determination (R2) or the adjuste…
