CHANGES
06/10/2014: Version 1.0.6
o On rare occasions jonckheere.test gave a p-value bigger than 1.
Sometimes 2*min(iPVAL, dPVAL, 1) can be larger than 1. Replace with
2*min(iPVAL, dPVAL, 0.5) (Thanks to Drs. Shterev and Owzar of Duke).
04/16/2013: Version 1.0.5
o Fixed the bound checks
01/22/2013: Version 1.0.4
o Added the option to calculate continuity corrected sample size in
the function gsdesign.binomial.
10/15/2012: Version 1.0.3
o Fixed two-sided p-value > 1 bug when statistic is exactly its mean.
o Fixed Rd file to address LaTeX warnings.
09/25/2012: Version 1.0.2
o integer overflow in djonck for the Jonckheere-Terpstra statistic.
replace with pdf calculation using Mark van de Wiel convolution.
o Create seperate help for functions permlogrank and jonckheere.test
08/14/2012: Version 1.0.1
o Fix integer overflow because of n0*n1 == 0 in roc.curve and
nn*nd == 0 in roc.area.test
o In coxphQuantile eliminate times for which survival probability
is 0 or 1 from quantile computation.
03/13/2012: Version 1.0.0
o Version number changed to 1.0.0 in preparation for R 2.15.
o toxbdry now does the entire Pocock to O'Brien-Fleming range of
boundaries. Added references for the method.
o Fixed linebreak in the help for coxphERR.
01/18/2012: Version 0.9.9
o Added coxphERR to calculate Heller's explained relative risk.
o Fixed NaN bug in toxbdry when priority="alt" is used.
09/13/2011: Version 0.9.8
o fixed bug in print.gsdesign for binomial case (p1,p2 instead of pC,pE)
o ROC functions now check that there are at least one each of status=0,1
04/27/2011: Version 0.9.7
o fixed fortran code to address gfortran-4.6 warnings
o added ktau a faster implementation of cor(x, y, method="k").
not in NAMESPACE. Should be called using clinfun:::ktau
04/25/2011: Version 0.9.7
o bug fix: roc.area.test integer overflow for large nn*nd.
o use sort function to speed up roc curve and area estimation.
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
