Tobias 1/01    pp.9--12; STB Reprints Vol 10, pp.90-93 Complete revision of diagtest to assess a simple diagnostic test in comparison with a reference standard; uses the exact binomial distribution and provides diagti, an immediate version of the commandVersion 1.1.3Posted on Kit Baum’s board http://fmwww.bc.edu/RePEc/bocode/d/diagt.hlphttp://fmwww.bc.edu/RePEc/bocode/d/diagt.adoCorrects some mistakes.Version 1.1.4written by Tom Steichenadded likelihoods (exact and approx)added -sf- option for Version diagt2First draft for version 2.0 (since abandoned) Included -wald- and -tb- optionsVersion 2.0To be written:To include LR+, LR-, OR, sum of Sensitivity & Specificity (name?) - DONETo correct any errors in version 1.1.3 - DONERe-write all to work through diagti. - DONECheck program, together with worked examples of all quantities and their CI. - partly done, does not include Tom Steichen’s stuff.Currently needed:Incorporate Tom Steichen’s suggestionsDone-sf- option: add 0.5 before working out likelihood ratiosDoneUpdate check program Version 2.0New layoutNew output:Odds ratios, ROC areas (av of sens & spec), likelihood ratios of positive and negative results.Perhaps CI for OR should be based on roctab, with bamber & hanley optionsPerhaps not.New options:-sf- , which uses “substitution formula (all 0.5 to each cell total before making estimates).-sf0-, which uses the substitution formula only in the presence of zeros New method:If -prev()- is used, confidence intervals are now given for the predictive values, based on those for the likelihood ratios.Help files have been revised.Version 2.03Draft - released for beta testing onlyVersion 2.04Draft - released for beta testing onlyVersion 2.05Add in Odds (option)Version 2.051 (of diagti only)Correct habit of giving 100% as 10%
