DTComPair 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.

DTComPair 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.

DTComPair 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.

DTComPair 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!
