bfpwr 0.3

• new contributor František Bartoš (https://orcid.org/0000-0002-0018-5573)
• add dirbf01() to compute directional z-test Bayes factors
• add point-null one-sided z-tests with truncated normal analysis priors via alternative = "less" or "greater"
• add one-sided normal moment priors via alternative = "less" or "greater"
• add sequential Bayes factor designs for z-tests and t-tests via pbf01seq() and ptbf01seq(), with stopping probabilities, expected sample sizes, summaries, and plots
• add sequential power and sample-size calculations via nbf01seq(), ntbf01seq(), powerbf01seq(), and powertbf01seq()
• add bfpwrOptions() to inspect and change session numerical settings
• improve numerical accuracy of small probabilities in pbf01() and pnmbf01(); fix pbf01() for very narrow normal priors and point alternatives identical to the null hypothesis
• improve numerical stability of one-sided tbf01() when observations strongly oppose the alternative hypothesis
• fix two-sided ptbf01() power and critical-value searches for shifted informed priors, including heavy-tailed priors
• improve accuracy of tbf01() for informed priors when the t-statistic and the prior point in opposite directions, where stats::dt() with a noncentrality parameter is unreliable
• add tail.eps to control the tail-probability cutoff in one-sided adaptive t critical-value searches, and tail.nquad to control the accuracy/speed tradeoff in one-sided t Bayes factor calculations (defaults: 1e-6 and 512)
• correct pbinbf01() power calculations for discrete binomial outcomes, including equality at the Bayes factor threshold

bfpwr 0.1.7

• added functions pbinbf01seq and powerbinbf01seq for sequential two-stage designs for binomial Bayes factors with futility stopping (https://doi.org/10.48550/arXiv.2511.23144)

bfpwr 0.1.6

• fixed a bug in ptbf01 when adaptively determining the search range

bfpwr 0.1.5

• update reference to published paper in The American Statistician (https://doi.org/10.1080/00031305.2025.2467919)
• fixed a bug in plot.power.bftest so that the correct data frame is returned for H0 (thanks Riko Kelter!)

bfpwr 0.1.4

• new functions related to Bayes factors for testing a binomial proportion: binbf01, pbinbf01, nbinbf01, powerbinbf01 (https://doi.org/10.48550/arXiv.2502.02914)

bfpwr 0.1.3

• changed citation in DESCRIPTION file to adhere to CRAN policy
• properly reset user’s par() in the vignette

bfpwr 0.1.2

• polished documentation based on feedback from Tsz Keung Wong (thanks!)
• changed name of sd argument to usd in nbf01, nnmbf01, pbf01, pbf01 to more clearly differentiate between the standard deviation of the data and the unit standard deviation related to a parameter estimate
