highly significantp -value < 0.0001
All regressions were highly significant ( F -value = 352.31, and p -value < 0.0001 for CLD % and F -value = 276.91, and p -value < 0.0036 for TS), and also the R 2 coefficients were adequate (0.988 for CLD %, and 0.998 for TS), demonstrating the models are suitable for representing the responses.
