ROPstat: A general statistical package useful for conducting person-oriented analyses

ROPstat is a wide scope statistical program package which offers specialties in three domains: 1) robust techniques, 2) ordinal analyses, and 3) pattern and person oriented methods. Many of them are not available in other common statistical softwares. In the present paper, first the general features and the main structure of ROPstat are briefly outlined, followed by a more detailed summary of pattern-oriented methods (detecting and imputing missing values, residual case identification, different types of classifications, post-analyses after classifications, etc.). In the last section we present some selected person-oriented scientific questions and show with real-life research data how they can be analyzed using ROPstat.
