A fast method for choosing the numbers of components in Tucker3 analysis

Recently, Timmerman and Kiers proposed an effective procedure for choosing the numbers of components in Tucker3 analysis, a kind of component analysis of three-way data. The procedure, however, is rather time-consuming, relying on very many complete Tucker3 analyses. Here, an alternative procedure is proposed, which basically relies on a single, quick analysis of the three-way data set. In a simulation study it was found that the new procedure is comparable in its effect to the original procedure.
