Hi all,
i'm modeling a survival problem about the duration of a treatment.
Patient leave the treatment following a mixed weibull distribution (2
weibull). The first are patient that returns to take drugs and the
latter are patient that ends the treatment because they don't want to
take drugs anymore. The two curves are obviously mixed as in this
figure
