CHANGES
03/24/2011: Version 0.9.6
o bug fix: roc.area.test gave NaN as the statistic and p-value when
the markers are identical. Changed it to 0.
03/09/2011: Version 0.9.5
o bug fix: gsdesign funtions not returning the sample size / # events.
02/24/2011: Version 0.9.4
o twostage.inference for umvue, p-value and CI for 2 stage design.
12/06/2010: Version 0.9.3
o ph2simon was testing whether dim is null for feasible solution.
Replaced with nrow == 0 since it is now possible to have 0 rows.
11/05/2010: Version 0.9.2
o Added functions to compute and plot the empirical ROC curve.
11/03/2010: Version 0.9.1
o Added functions for the area and permutation tests to compare ROC.
o Checks that min.diff is greater than 0 in pselect.
11/01/2010: Version 0.9.0
o Added a non-binding futility boundary to gsdesign
04/16/2010: Version 0.8.10
o variable names for returned data.frame in coxphQuantile
o examples in coxphQuantile & coxphCPE use status==2
04/09/2010: Version 0.8.9
o check Rversion so that coxphCPE works for any version (see 0.8.9)
04/07/2010: Version 0.8.8
o Change coxphCPE to reflect the fact that model.matrix.coxph doesn't
have an intercept term.
02/25/2010: Version 0.8.8
o Added the function or2pcase
11/20/2009: Version 0.8.7
o Fixed the 0/0 bug in the revised pselect
11/17/2009: Version 0.8.6
o Changed Venkat's affiliation to MSKCC.
o Fixed pselect to calculate the selection probability correctly when
only one treatment exceeds the min.resp threshold.
07/10/2009: Version 0.8.5
o Changed the Jonckheere-Terpstra statistic such that large value is
indicative of increasing group locations and small for decreasing.
Function warns that p-value is based on approximation for tied data.
12/02/2008: Version 0.8.4
o Added functionality to pselect. It can do unequal sample size for
the case of two treatments. min.diff can be specified as a rate
instead of number of responses. Output element names changed to be
more descriptive.
11/18/2008: Version 0.8.3
o Fixed the bug CPS.ssize. call inside used fixed alpha, power & r.
09/18/2008
o Fixed the bug in the approximate one-sided p-value of Jonckheere
test. wrong tail was used.
06/20/2008: Version 0.8.2
o toxbdry allows the error threshold to prioritize when the sample
size is too small to have both satisfied.
06/17/2008: Version 0.8.1
o Fixed gsdesign to allow for fixed sample designs. Help file fixed.
05/23/2008: Version 0.8.0
o New version with one new function power.lehmann.design
