The Editor-in-Chief has retracted this Article. The article was accepted as part of a guest-edited special issue in Current Psychology. Before the special issue was finalized, the Editor-in-Chief detected problems with editorial handling and peer review and decided not to proceed with the special issue. Post publication peer review found the following issues:

  • The validity of the method cannot be confirmed because of insufficient explanation of the methods.

  • The results concerning the predictive power of the proposed method are unreliable due to the lack of verification by an out-of-sample test or cross validation test.

  • There are errors in the figures and tables regarding the results. Specifically, the graph in Figure 1 appears to have been repeated and the contents of Tables 3 and 4 are identical.

The Editor-in-Chief therefore no longer has confidence in the reliability of the work presented. None of the authors of this article have responded to correspondence about the retraction note from the Editor-in-Chief.
