Examples in Context

  1. Based on fundamental parameters method, the number of factors in XRF multi-variation calibration system has been estimated through the calculation of PRESS ( predictive residual error sum of squares ) and the analysis of principal component.
  2. The calibration models were established by using single wavelength regression, multiple linear regression, principal component regression, partial least square regression and artificial neural network. The accuracy of the calculated results was estimated with predictive residual error sum of squares ( PRESS ).
  3. A numerical example of carbonization process in an aluminium-making plant indicates that the PRESS ( Prediction Error Sum of Squares(ESS) ) of the model from our method is lower than that from conventional regressions, and the predictor derived from the present work is more robust.
  4. To compare the validity of settlement prediction with different principia, superior combination forecasting based on forecasting effective measure is much better than the traditional combination forecasting, which modeled on the minimal value of error sum of squares or the deviation absolute sum.
  5. By calculation of all possible regressions with Mallows ' C_p statistic, average predic-tion mean square error ( S_p ) and prediction sum of squares ( PRESS ), the optimum fore-casting model can be obtained.
