Abstract

We discuss several methods to realize three-way (three mode) approaches to clustering using the INDCLUS model and multidimensional scaling using the INDSCAL model, which assumes that the objects are embedded in a discrete or continuous space common to all data, including individual differences obtained by weighting each dimension. We apply some effective dynamic graphical approaches using two methods to perform a time-space structural analysis for multivariate spatial time series. The clustering and scaling of multivariate spatial time series consider: (1) the spatial nature of the objects to be clustered geometrically (discrete); (2) the characteristics of the feature space with the time series (continuous); (3) the latent structure between space and time. The last aspect is addressed using dynamic graphics with a matrix-type presentation. We can simultaneously observe the spatial nature, move the feature space and can zoom in/out of the results using a suitable size. The proposed analysis can be applied to the classification and scaling of the prefectures of Japan on the basis of the observed dynamics of some safety indicators.
