“…for MLP the number of hidden layers and the therein covered numbers of nodes, or in case of Partial Least Square/Projection to Latent Structures (PLS) the number of latent variables) can be addressed with the Akaike Information Criterion or Bayesian Information Criteria, the latter being more suitable for models with large numbers of parameters (Lee, Vanrolleghem, & Park, 2005;Peres, Oliveira, & de Azevedo, 2008;von Stosch, Peres, de Azevedo, & Oliveira, 2010). Also other statistical criteria can be applied (Bollas et al, 2003;Kim & Chang, 2000) to evaluate the estimations obtained with different sized nonparametric models.…”
