How to analyse heterogenous data?

Date of publication: February 1, 1978

Abstract:

In many cases, data collected in the same questionnaire are measured at different levels: nominal, ordinal, interval or ratio. For several years, new methods allow to analyse qualitative and/or heterogeneous data. They are based on the optimal quantification principle. In this paper we first give a detailed example of heterogeneous data analysis. Then we describe the optimal quantification principle and the most important methods. Finally we give practical examples in marketing research.
