Multiple correlation coefficient (R) for prediction
of TSS could further be increased to 0.96 and 0.73, respectively,
for calibration and validation using MLR model in the wavelength
range of 329.685–358.612 with corresponding R values for PLS
model being 0.87 and 0.81, respectively, indicating MLR model is
better suited for prediction of TSS, although the larger difference
in R values of calibration and validation may prove unstable during
prediction.
