%description
Given constraints for right censored data, we use a recursive
computational algorithm to calculate the the "constrained" Kaplan-Meier
estimator. The constraint is assumed given in linear estimating equations
or mean functions. We also illustrate how this leads to the empirical
likelihood ratio test with right censored data and accelerated failure
time model with given coefficients. EM algorithm from emplik package is
used to get the initial value. The properties and performance of the EM
algorithm is discussed in Mai Zhou and Yifan Yang (2015)<doi:
10.1007/s00180-015-0567-9> and Mai Zhou and Yifan Yang (2017) <doi:
10.1002/wics.1400>. More applications could be found in Mai Zhou (2015)
<doi: 10.1201/b18598>.
