Changes in version 1.2.6 (2024-09-24) - The functions acc.1test() and acc.paired() now allow the user (via the argument method.ci)to choose from a range of differnt types of confidence intervals. Changes in version 1.2.4 (2024-04-10) - The functions tab.paired() and tab.1test() now allow for data where all subjects are either diseased or nondiseased. - A link to a package website and a hex sticker have been added. Changes in version 1.2.2 (2023-08-20) - Functions that compare sensitivity/ specificity and predictive values now return lists of vectors (instead of lists of lists). - Test 1 is consistently used as the reference test. - In pv.gs()and pv.wgs(), it is now diff.ppv <- ppv.2-ppv.1 (instead of diff.ppv <- abs(ppv.1-ppv.2)), and accordingly for negative predictive values. - Added a new function (pv.prev()) to allow computation of positive and negative predictive values for different theoretical prevalences. - Added a new function (sesp.gen.mcnemar()) implementing a generalized McNemar's test for a joint comparison of sensitivity and specificity. - A redundant table in man/dtcompair-package.rd was deleted. Changes in version 1.2.0 (2023-04-21) - pv.rpv() now returns the full variance-covariance matrix (Sigma). - ellipse.pv.rpv() generates the data to plot a joint confidence region for rPPV and rNPV (depends on the ellipse package) (as in Moskowitz and Pepe, 2006). - sesp.rel() calculates relative sensitivity and relative specificity (with Wald CIs and p-value). - tpffpf.rel() calculates relative sensitivity (rTPF) and relative 'one minus specificity' (rFPF) (with Wald CIs and p-value), but it does not calculate their individual components (ie, TPFs and FPFs); this function is meant to be used with paired screen-positive designs, where only rTPF and rFPF are estimable form the data (see Cheng and Macaluso, 1997 or Alonzo, Pepe, Moskowitz, 2002). - The new features were contributed by A. Discacciati - many thanks! Changes in version 1.1.0 (2023-02-23) - Restored compatibility with CRAN requirements. Changes in version 1.0.3 (2014-02-16) - Corrected an error in sesp.diff.ci (detected by F. Gimenez - many thanks!). - Minor documentation update. Changes in version 1.0.2 (2013-11-15) - Corrected an error in function sesp.exactbinom (detected by J. Swiecicki - many thanks!). - Minor documentation update.
