In the EU Territorial Agenda 2024 building on the ESDP, there is a growing understanding of the importance of balanced, sustainable and integrated territorial development, taking into account functional links in and between territories, notably rural and urban areas (Slavova 2024). Witrynaof scalogram analysis have been unaware of the most important developments in this area. This is suggested by the fact that the most widely distributed computer program for scalogram analysis contains virtually no discussion of the possibility of capitalizing on chance factors in such analyses and pro-vides no test of significance at all 1 (Dixon,
