Notes.—P values are marked with asterisks to highlight their significance level, where double and triple asterisks indicate P values below a threshold of 0.01 and 0.001, respectively. Column 3 lists partial correlation coefficients, where statistical significance is identical to the MLR analysis. Column 4 lists the amount of variation explained by each of the explanatory variables according to PCR.
