Power2StageV0.5-4

Bug fixes

• False df for n2>0 in sampleN2.TOST() fixed.

Minor changes

• LazyData: yes entry from DESCRIPTION removed since no data folder was available. Caused a NOTE during R CMD check instead of Ok.

Power2StageV0.5-3

Bug fixes

• Subtract/add .Machine $double.eps if rho ±1 in power.tsd.2m() to prevent error in rWishart().

Major changes

• Argument min.n2 introduced in power.tsd.p().
• README.md knitted from README.Rmd.
• NEWS.md instead of NEWS.

Minor changes

• Badges in READMEs like in PowerTOST, session_info() added.
• Argument min.n2 in man-pages of power.tsd() and power.tsd.fC() more correctly explained.
• Stop interim.2stage.in() if n1 <3 and final.tsd.in() if n1 | n2 <3 (avoids errors and warnings).
• References in man-pages of *.tsd.in() corr.
• Refined printing of results for interim.tsd.in() and power.tsd.in().
• Make internal power (and sample size) function more consistent wrt different alphas

Power2StageV0.5-2

• Maintenance release with mainly bug fixes.
• Bug fix in calculation of median unbiased estimate within final.tsd.in().
• Typos and minor wording and formatting corrections (man pages and x.tds.in()).
• Bug fix in power.tsd.GS (regarding variable hw).
• Bug in interim.tsd.in() w.r.t to power > target triggering futulity fixed (THX to mittyri).

Power2StageV0.5-1

• All functions xyz.2stage.ab() now have an alias xyz.tsd.ab(), e.g. instead of power.2stage.fC() one may use power.tsd.fC(). The versions with .2stage. in their names will be removed in later versions.
• The futility rule for a CI in power.2stage.GS() now based on 90% CI to be in line with the other functions using such a futility rule.
• Default fCrit in power.2stage.GS() changed to "CI".
• Added interim.2stage.in() and final.2stage.in() to perform interim and final analysis of 2 stage designs based on the Standard Combination or Maximum Combination Test (also includes a print class).
• Update defaults of power.2stage.in() in order to be consistent with Paper from Maurer et al (2018).
• Experimental function power.tsd.2m() to deal with 2 PK metrics in the TSD decision scheme Potvin "B". Not public yet.

Power2StageV0.4-6

• Updates of various man pages.
• New function sampleN2.TOST() to estimate n2 in 2x2 and parallel designs
  based on df=n-3 for stage 2.
• df for sample size re-estimation changed to n-3 for Potvin like TSD schemes
  (pooled evaluation with additionally stage term)
• Same for power.2Stage.ssr().
• Function power.2stage.in() to calculate the operational characteristics of
  TSDs evaluated via p-value combination using the inverse normal approach.
