Factors in the metabolites (top plots) and time (bottom plots) modes extracted from the real versus simulated data using a 3-component CP model. The vectors \({{\mathbf {{b}}}}_{1}\), \({{\mathbf {{b}}}}_{2}\) and \({{\mathbf {{b}}}}_{3}\) are the components in the metabolites mode, and vectors \({{\mathbf {{c}}}}_{1}\), \({{\mathbf {{c}}}}_{2}\) and \({{\mathbf {{c}}}}_{3}\) are the temporal patterns extracted by the CP model. Model fits for the real and simulated data are 50.3% and 71.6%, respectively
