the mean relative error for the Henderson model being lower than for the others (MRE ¼ 8.7%).
Residual analysis to Henderson model (Figure 5) showed
absolute residuals less than 6.1 10−3 kg · kg−1 (d.b.), with
80.6% of the values below 3.0 10−3 kg · kg−1 (d.b.).
According to the Lilliefors test, residuals exhibited no
deviation from statistical normality (p > 0.05) showing
that the fit of Henderson model was adequate.
