, but as presented here has added columns; no NAs.
Poison
Factor with three levels I, II, and III.
Treatment
Factor with four levels, A, B, C, and D.
Group
Factor with 12 levels, 1:12.
SurvTime
Numeric; survival time.
RateSurvTime
Numeric; inverse of SurvTime
RankRateSurvTime
Numeric; RateSurvTime
scores have been converted to ranks, and then rescaled to have the same median as and a spread comparable to RateSurvTime
