Multilevel analysis with application of symbolic data

Summary/Abstract: The paper proposes the application of symbolic data analysis in the context of multilevel analysis. Multilevel analysis allows for taking into account heterogeneity of the data and the fact that respondents may be “nested” in many different functional elements. The main aim of the paper is the estimation of multilevel regression models for investment strategies in Polish households. The empirical part shows the results of the research for Polish households. The results suggest that symbolic data analysis may be a useful tool for multilevel analysis of data. It allows for describing objects in more detailed way – both at individual and aggregate level.
