| dc.description.abstract | Carrying out a statistical analysis the researcher is concerned with the problem of choosing an appropriate statistical technique from a large number of competing methods. Most common statistical software offer different methods for analysing the data without giving any support concerning the adequacy of a method for a particular data set. This paper outlines the main features of the computer system CORA which provides a statistical analysis of stratified contingency tables and additionally supports the researcher at the different steps of this analysis. Here, the support given by the system consists of two different aspects. On the one hand, the help system of CORA contains general information on the implemented statistical methods which can be obtained on request. On the other hand an advice tool recommends an adequate statistical method which depends on the actual empirical casecontrol data to be analysed. To build up the advice tool a set of rules being discovered by machine learning from simulation studies is integrated into the system CORA. The paper is written in English. | en |
