albatross (version 0.1-1)

PARAFAC Analysis of Fluorescence Excitation-Emission Matrices

Description

Perform parallel factor analysis (PARAFAC: Harshman, 2005) ) on fluorescence excitation-emission matrices (FEEMs): handle scattering signal (Bahram, 2007) and inner filter effect (Kothawala, 2013) , scale the dataset, fit the model; perform split-half validation (DeSarbo, 1984) or jack-knifing (Riu, 2003) . The package has a low dependency footprint (only two direct dependencies not in core or recommended; four total non-core/recommended dependencies) and has been tested on a wide range of R versions (including R as old as 3.3.3 from Debian Stretch).
