Details

These are not intended to be called by the user.

Wdataclean2 and DnR are used by the functions emplikH1.test, emplikH2.test and emplikdisc.test. It is also used by LTRC.

DnR take the survival data as input, compute the number at risk and number of observed events, and output only those time points where there is some events. Notice the input must be ordered! We should use Wdataclean2/3/5( ) first and then use the output there as the input of DnR.

Wdataclean2 will sort the data and collapse those that are true ties, and the number of tied value is in the weights.

logelr, llog, llogp and llogpp are used by function el.test. They are from Owen.

Wdataclean2, WKM and solve3.QP are used by function el.cen.test. WKM() is the weighted Kaplan-Meier.

WCY is the weighted Chang and Yang self-consistent estimator for doubly censored data.

Wdataclean2 is used by el.cen.EM.

LTRC is for Left Truncated and Right Censored data.

gradf3 is used by the function emplikHs.test2. (and stored there)

el.test.wt3 are similar to el.test.wt and el.test.wt2, but can take vector mean as constraint. llog, llogp and llogpp are used by both el.test.wt3 and el.test.wt2. In addition logwelr is used by el.test.wt3.

MMRtime estimate the Mean and Median residual life time at age with right censored data.

iter is for perform one iteration of EM in the Buckley-James censored regression estimation. redistF is for redistribution of probability, according to Fdist. Used in BJtest() and BJtestII().

cumsumsurv is similar to rev(cumsum(rev( ))) but faster. omega.lambda is a recursive function, either R or C (future), to compute jumps of KaplaMeier given Lagrange multiplier lambda. emplikHs.test22 similar to emplikHs.test2; and is used by RankRegTestH() only.
