(2002) obtained higher values of repeatability, with three to seven cycles of measurements indicated as sufficient to predict the real value of the palm heart production characters, with

coefficient of determination higher than 85%.

Table 6 summarizes the results of the experimental verification for three different types of models in the form of the mean relative error MRE and the

coefficient of determination [R.sup.2].

Fitted models for the leaf area (LA, [cm.sup.2] per leaf) of Acca sellowiana, adjusted

coefficient of determination ([R.sup.2]), mean absolute error (MAE) and concordance correlation coefficient (CCC), according to the dimensions of the leaves: width (W) and length (L) of leaf blade Equation [R.sup.2] MAE CCC (%) Mod.

The value of

coefficient of determination, [R.sup.2] is 0.517 or 51.70% which indicates that around 52% of variation in the dependent variable (CAR) can be explained by the independent variable (NPL) in the above mentioned regression model.

For the SIN IgG2 subclass, the

coefficient of determination with the LC-MS/MS IgG subclass measurements was also improved when multivariate linear regression incorporating both IgG2 and IgG4 ([R.sup.2] = 0.74) was used compared with using LC-MS/MS IgG2 alone ([R.sup.2] = 0.46; Table 2).

The median values of the

coefficient of determination ([R.sup.2]) of all semimeridians in the two groups were both above 0.9.

The linearity was evaluated at 8 levels of concentration and in the two methodologies with a

coefficient of determination > 0.98.

Coefficient of Determination (R2) was identified, in which the highest result was X1.1 Quality standards (0.913)

In relation to the

coefficient of determination ([R.sup.2]) of the obtained equations, the AFLi-Cor and AFReal relationship (Figure 1A, B and C) presented satisfactory fits of the points to the line, with determination coefficient of 0.79; for small leaf, 0.84 for medium leaf and 0.93 for large leaf when classified by leaf size and 0.97 when disregarding leaf classification (Figure 1D).
