  "Description": "Programs to find the sample size or power of studies using\nthe Sequential Parallel Comparison Design (SPCD) and programs\nto analyze such studies. This is a clinical trial design where\npatients initially on placebo who did not respond are\nre-randomized between placebo and active drug in a second phase\nand the results of the two phases are pooled. The method of\nanalyzing binary data with this design is described in\nFava,Evins, Dorer and Schoenfeld(2003) <doi:10.1159/000069738>,\nand the method of analyzing continuous data is described in\nChen, Yang, Hung and Wang (2011)\n<doi:10.1016/j.cct.2011.04.006>.",
