The coefficient of determination, standard error of estimate, mean relative percent deviation and the nature of residual plots were used to evaluate the goodness-of-fit.
We used a conservative 2-bp allelic category size determination standard error range for reproducibility and the 2-bp resolution of the QIAxcel Capillary Electrophoresis System.
To assess the improvements made in the method development and to assess the bias in the prediction, linear regression of PE measured versus predicted in the training set was used and the coefficient of determination (R), adjusted coefficient of determination (Radj), standard error of estimate, and analysis of variance of the regression were checked.
The predicted values obtained for protein yield revealed that coefficient of determination and standard error was 0.80 and 0.906, respectively.
The following statistics were used as selection criteria: adjusted coefficient of determination (R2), standard error of the absolute estimate (Syx) and percentage (Syx%), as well as graphical analysis of residuals.
Jack-knife algorithm has been incorporated for determination of standard error for parameters.
The following statistics were used as selection criteria: adjusted coefficient of determination (R), standard error of the absolute estimate (Syx) and percentage (Syx%), as well as graphical analysis of residuals.
R: adjusted coefficient of determination; Sy|x: standard error of the estimate; SEM: standard error of the mean; NA: not applicable; Bold numbers: not statistically different from zero, invalid parameter.
Stepwise regression analysis within diets resulted in greater coefficient of determination and lower standard error values.
Table 1 Simple linear regression equation of AOPD and yield at AOPD (Y) over hybrid release years (X) fitted at different hierarchical steps of modeling, coefficient of determination (R2), and standard error (SE) of the slope of the models.
