The tests are based onL.Wilkinson's "Statistics Quiz". Systems under test included BMDP, Data Desk,Excel, GLIM, ISP, SAS, SPSS, S-PLUS,STATGRAPHICS. The results showconsiderable problems even in basic features of well-known systems. For allour test exercises, the computational solutions are well known. The omissionsand failures observed here give some suspicions of what happens in lesswell-understood problem areas of computational statistics. We cannot takeresults of data analysis systems at face value, but have to submit them to alarge amount of informed inspection. Quality awareness still needs improvement. date: 1994-07 id_scheme: DOI id_number: 10.11588/heidok.00021473 schriftenreihe_cluster_id: sr-10b schriftenreihe_order: 01 ppn_swb: 1657867307 own_urn: urn:nbn:de:bsz:16-heidok-214736 language: eng bibsort: SAWITZKIGUTESTINGNUM199407 full_text_status: public place_of_pub: Heidelberg pages: 36 citation: Sawitzki, Günther (1994) Testing Numerical Reliability of Data Analysis Systems.
