title: Testing Numerical Reliability of Data Analysis Systems creator: Sawitzki, Günther subject: 510 subject: 510 Mathematics description: From 1990 to 1993, a series of tests on numerical reliability ofdata analysis systems has been carried out. 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 type: Working paper type: info:eu-repo/semantics/workingPaper type: NonPeerReviewed format: application/pdf identifier: https://archiv.ub.uni-heidelberg.de/volltextserverhttps://archiv.ub.uni-heidelberg.de/volltextserver/21473/1/report.01.pdf identifier: DOI:10.11588/heidok.00021473 identifier: urn:nbn:de:bsz:16-heidok-214736 identifier: Sawitzki, Günther (1994) Testing Numerical Reliability of Data Analysis Systems.
