norm2A

Factors used for normalisation are saved separately in the PARAFAC models. With this function, the normalisation factors are combined with the A-modes of the model and removed as a separate vector. This means former normalisation is accounted for in the amount of each component in each sample. If no normalisation was done, the original model is returned without warning.

This is a user-friendly way to run a parallel factor (PARAFAC) analysis (Harshman, 1971) <doi:10.1121/1.1977523> on excitation emission matrix (EEM) data from dissolved organic matter (DOM) samples (Murphy et al., 2013) <doi:10.1039/c3ay41160e>. The analysis includes profound methods for model validation. Some additional functions allow the calculation of absorbance slope parameters and create beautiful plots.
