Reply to ‘Comment on “A multivariate model based on dominant factor for laser-induced breakdown spectroscopy measurements”’ by Vincenzo Palleschi, J. Anal. At. Spectrom., 2011, DOI: 10.1039/c1ja10197h

Abstract

In the previous article, Palleschi wrote a comment to our recently published paper “A multivariate model based on dominant factor for laser-induced breakdown spectroscopy measurements” (Z. Wang, J. Feng, L. Li, W. Ni and Z. Li, J. Anal. At. Spectrom., 2011, DOI:10.1039/c1ja10041f),¹ in which we proposed a dominant factor based PLS model. He commented that the proposed method is basically flawed since the predictions of the model are worse than the ones obtained using standard univariate approach based on calibration curve. In this reply, we try to further clarify our dominant factor based PLS model and to remove the misunderstanding. We strongly believe that our new proposed multi-variate model outperforms the conventional PLS model.
