- W3014244428 abstract "Model evaluation is used to derive model performance index that indicates practical values of prediction model. In practice, it occurs in the last step of the statistical modelling pipeline; and various types of model evaluation methods or strategies have been proposed in the literature. Iterative resampling strategy is believed to be more reliable than sampling approach like Kennard-stone algorithm because it produces more than one test set to ensure better representativeness. Most of the iterative resampling methods available in commercial statistical software implement random resampling by default. This would produce biased estimator if the studied dataset is imbalanced, i.e. unequal group sizes. As a result, stratified resampling has been proposed to ensure similar class proportions in both the test and training sets. This preliminary work aims to explore empirical differences between stratified and random iterative sampling strategies in assessing performances of partial least squares-discriminant analysis (PLS-DA) model using imbalanced attenuated total reflectance-Fourier transform infrared (ATR-FTIR) spectra of blue gel pen inks. The dataset consisted of 1361 spectra and 5401 variables; and can be classified into ten different pen brands (i.e. groups). The findings demonstrate the merit and pitfalls of the two resampling strategies." @default.
