%description
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.
