ratesci 0.4-0.9000 (yyyy-mm-dd)

New features

Bug fixes

• In scoreci(), improved handling of special cases for MN weighting (#25, thanks to Vincent Jaquet for reporting the issue and proposed solution. Also #27 for RR, thanks to Shangchen Song.)

Other

ratesci 0.4-0 (2021-12-04)

New features

In scoreci():

• MN weighting now iterates to convergence (@jonjvallejo, #20).
• Added optional prediction interval for random effects method (also in tdasci()).
• Added xlim and ylim arguments to control plot output.
• Added sda & fda arguments for optional sparse/full data adjustment when x1 + x2 = 0 or x1 + x2 = n1 + n2 in a stratum.
• Added INV option for weights that omit the variance bias correction.
• Added RRtang argument to apply Tang's alternative score for RR (recommended for stratified analysis with INV/IVS weights. Experimental for Poisson RR). Stheta = (p1hat - p2hat * theta) / p2d (see Tang 2020)
• Added simplified skewness correction option (causes p-values to be omitted, see Tang 2021 & Laud 2021).
• Introduced warning and plot features for very rare occasions when quadratic skewness correction cannot be calculated due to a negative discriminant.
• p-value suppressed where affected by negative discriminants.
• Changed ORbias default to TRUE (see Laud 2018).
• Changed weighting default to MH for RD & RR, INV for OR (for consistency with CMH test).
• Added hetplot argument to separate heterogeneity plots from score function plot.
• Uninformative strata are now retained in the analysis except if:
• contrast = OR with MH weighting;
• contrast = RR with IVS/INV weighting if RRtang = FALSE;
• random = TRUE (needs further evaluation);
• excluded using new option dropzeros = TRUE.

In tdasci():

• Default uses skew = TRUE for stratum CIs.

Bug fixes

• MN weighting in scoreci() corrected for distrib="poi".
• Fixed bug in scoreci() for calculation of stratum CIs with random=TRUE.
• Fixed bug in scoreci() for distrib = "poi" and contrast = "p" (#7).
• Fixed finite precision bug in scaspci().
• Fixed bug in rateci() for closed-form calculation of continuity-corrected SCAS.
• Fixed bug in scoreci() for stratified zero scores calculated as NA, resulting in UL = 0. (Thanks to Lidia Mukina for reporting the bug.)
• Fixed variable plot ranges for vectorised inputs.

Other

• Renamed tdas argument to 'random'.
• Removed redundant t2 variable.

ratesci 0.3-0 (2018-02-15)

New features

• Added bias correction in scoreci() for OR SCAS method (derived from Gart 1985).
• Added score methods (Tango & Tang) as default for paired binomial RD and RR in pairbinci().
• Added transformed mid-p method for paired OR for comparison with transformed SCAS.
• Added scaspci() for non-iterative SCAS methods for single binomial or Poisson rate.
• Added rateci() for selected methods for single binomial or Poisson rate.

Bug fixes

• Fixed bug in pairbinci() for contrast="OR".
• Fixed bug in moverci() for contrast="p" and type="wilson".
• Corrected error in cc for stratified SCAS method for OR.
• Clarified documentation regarding continuity corrections.
• Set Stheta to 0 if |Stheta|<cc in scoreci()
• Fixed stratified calulations for contrast = "p" in scoreci().

ratesci 0.2-0 (2017-04-21)

New features

• Added pairbinci() for all comparisons of paired binomial rates.
• Added option to suppress warnings in scoreci.
• Added Galbraith plot (for assessing stratum heterogeneity) to scoreci().
• Added qualitative interaction test to scoreci().
• Added stratum estimates & CIs to scoreci() output when stratified = TRUE.

Bug fixes

• Fixed bug for contrast = "p" in moverci().
• Fixed bug in tdasci() wrapper function.
• Fixed bug for stratified OR.
• Altered adjustment options for boundary cases in moverci().
• Changed point estimate used in moverci() to posterior median for type = "jeff", to ensure consistent calculations with informative priors.
