It is also being referred to as the coefficient of determination, or the coefficient of multiple determination for multiple regression.
However, from overall, the RSD values in all repeatability and reproducibility tests were satisfactory and showed that the methods used were reliable to produce precise data for multiple determinations of fatty acids (saturated and unsaturated) in fish and shellfish samples, both in a single-day and multiple-day determinations.
Since multiple determinations of plasma vitamin C levels for assessing subjects' actual vitamin C status were not possible in our study, we opted against obtaining an one-time determination.
According to analysis of variance (ANOVA) the coefficient of multiple determination of 0.841 was obtained for RSM and 0.974 for ANN.
Based on previous HPLC-MS/MS methods for the multiple determination of mycotoxins in cereals developed in our group [ 4, 7], we created a new multi-target ultra-high-performance liquid chromatographic tandem mass spectrometric (UHPLC-MS/MS) method which covers a total number of 191 fungal metabolites.
The best statistical coefficient of multiple determinations (R2-value) for training data equals to 0.999715, 0.995627, 0.999497, and 0.997648 obtained by different algorithms with seven neurons for the non-dimensional exergy losses of evaporator, generator, absorber and condenser, respectively.
We built up two prediction rules ("Snap-shot rule" for a single sample and "Track-shot rule" for multiple determinations) based on a systematic review of published longitudinal analyses of CD4 cell count trajectories.
Average recoveries were > 50% for all compounds except for PFOSA, PFDA, PFUnDA, and PFDoDA (34 47%) and the coefficient of variation (CV) was 2 27% for multiple determinations.
In our case, with double anaerobic bacteria etiology and multiple determinations, interdisciplinary collaboration was essential for a good outcome.
The statistical coefficient of multiple determinations (R2 value) equals to 1, 0.9996, 1 for the COP, ECOP and F, respectively.
