tsdf 1.1-9 (2026-04-25)

• Improved computational efficiency.

tsdf 1.1-8 (2020-05-09)

• Added function "adj.two" to handle overrunning and underrunning designs.
• Changed error precision to 4 decimal places in "opt.design".
• Replaced option 'pt' with 'pe' in "opt.design".
• Replaced option 'two.sided' with 'stop.eff' in "opt.design".
• Resolved CRAN issues.

tsdf 1.1-7 (2019-05-31)

• Fixed a bug that caused incorrect type II error calculations for phase 2 designs.
• Added "two.sided" option for phase 2 three-stage designs.
• Added an alpha-spending function (the gsDesign package is no longer required).

tsdf 1.1-4 (2018-01-11)

• "dec.sim" now reports the probability that each dose level is selected as above the maximum tolerated dose (MTD).
• Updated the dose-finding simulation algorithm to provide a more accurate MTD when the decision is "E".
• Changed the parameter name in Phase I dose-finding from pc to pt.
• Phase I designs are now referred to as the Target Toxicity Design.
• Added option "pe.par" to "dec.table" to calculate the true type II error.

tsdf 1.1-3

• "dec.table" now supports the HSD spending function.
• Removed option "pc.u" from "dec.table".
• Removed option "sf" from "dec.table".
• Added option "sf.param" to "dec.table" for greater flexibility.
• Updated vignettes.

tsdf 1.1-2 (2017-09-06)
