A meta-analytic comparison of determinants of public transport use: methodology and application

Our aim in this paper is to apply principles from modern meta-analysis to i dentify differences and commonalities in patterns of explanatory variables for varying price elasticities for public transport in different countries. In addition to the synthesis and analysis of empirical data on these elast icity values with a view to selection of the main determinants of significa nt cross-national differences, a series of different analytical methods (no tably rough set analysis, cluster analysis, and discriminant analysis) are applied in order to test not only the robustness of the results, but also-b y way of a 'meta-meta-analytic' experiment-the variations in research findi ngs caused by the use of different methods.
