The parsimony principle

Webb28 maj 1993 · The general principle of parsimonious data modeling states that if two models in some way adequately model a given set of data, the one that is described by a fewer number of parameters will have better predictive ability given new data. This concept is of interest in multivariate calibration since several new non-linear modeling techniques … Webb28 maj 1993 · In this paper, the mathematical theory of parsimonious data modeling is presented. The assumptions made in the theory are shown to hold for multivariate calibration methods. This theory is used to provide a procedure for selecting the most parsimonious model structure for a given calibration application. Keywords Multivariate …
