“…One advantage of the HJ-biplot method is that it interprets information about the relative situation of the points with respect to the variables with greater or less preponderance (González-Cabrera et al, 2006). We use the HJ-biplot method rather than more conventional approaches (e.g., a principal-component analysis, a factorial analysis) for its important advantages.…”

“…According to González-Cabrera et al (2006), several measures are essential for a correct implementation of the HJ-biplot, including eigenvalues and explained variance (Table 1) and the factor's relative contribution to the element (Table 2). Through this contribution, it is possible to detect the variables responsible for the position of axes and, therefore, the configuration obtained in them.…”

“…It was demonstrated that the HJ-Biplot was able to produce better results than the previous classic biplot methods [14] since this method achieves an optimum representation quality for both rows and columns, because they are represented in the same system [14,17,18].…”

“…For the analysis of rankings of sustainability, multivariate techniques also may be used. One of them is the HJ-Biplot [14], which have a variety of studies [15,16,[16][17][18][19] and may be combined with cluster analyses [15,16]. Xavier and Costa Freitas [16] showed the great potential of this approach to analyse agricultural dynamics and identify trends.…”

“…Using the HJ-Biplot method instead of other conventional techniques, such as principal component and factor analysis, we gain important advantages. The axes in principal component analysis are combinations of variables, but they do not appear on the plots, so important information is lost, such as the situation of individuals with respect to characteristics (González-Cabrera et al, 2006). Thus, biplot analysis is more representative in showing the situation of Portuguese local governments according to public service delivery.…”
