eempf_leverage_ident

Plot is interactive where you can select values with your mouse. A list of vectors is returned to remove this outliers in a further step from your samples. The labels to be shown can be selected by adding the quatile of samples with highest leverages to be labeled.

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.
