  1. Average errors (E) in prediction of absorption and reduced scattering coefficients are presented for two types of data sets: simulated (uniformly-distributed optical properties) and measured (randomly-distributed optical properties). Case A includes evaluation for the entire optical property range whereas for Case B, samples with μa < 5 cm-1 are omitted.
