Description Usage Arguments Value Examples
A function finds parameter h of a uniform dropout censoring distribution U(0,h) with a generalized gamma survival distribution or a log-logistic survival distribution for a given dropout censoring probability.

lfu |
the dropout censoring probability. |
R |
the recuritment duration. |
T |
the study duration. |
q, mu, sigma |
shape, location and scale parameters of an assumed generalized gamma distribution for the control arm. A character string q="LLG" indiactes an assumed log-logistic survival distribution F_0(y;ξ,ζ)=1/(1+(y/ξ)^{-ζ}) for the control arm, where ξ = mu and ζ = sigma. |
eta, theta |
parameters of the entry distribution with η ≥ -θ/R and η >0 (θ=0 for the uniform dropout censoring). |
the parameter h of the uniform dropout censoring distribution U(0,h).
