vdar swMATH ID: 38403 Software Authors: Solveig Pospiech, K. Gerald van den Boogaart Description: R package vdar: Discriminant Analysis Incorporating Individual Uncertainties. The qda() function from package ’MASS’ is extended to calculate a weighted linear (LDA) and quadratic discriminant analysis (QDA) by changing the group variances and group means based on cell-wise uncertainties. The uncertainties can be derived e.g. through relative errors for each individual measurement (cell), not only row-wise or column-wise uncertainties. The method can be applied compositional data (e.g. portions of substances, concentrations) and non-compositional data.
