Selecting relevant predictors: impact of variable selection on model performance, uncertainty and applicability of models in environmental decision making Universiteit Gent
One of the crucial steps when developing models is the selection of appropriate variables. In this research we assessed the impact variable selection on the model performance and model applicability. Regression trees were built to understand the relationship between the ecological water quality and the physicalchemical and hydromorphological variables. Different model parameterizations and three combinations of explanatory variables were used ...
