G. Gomez et Sw. Lagakos, ESTIMATION OF THE INFECTION TIME AND LATENCY DISTRIBUTION OF AIDS WITH DOUBLY CENSORED-DATA, Biometrics, 50(1), 1994, pp. 204-212
We consider the nonparametric estimation of the time to infection with
HIV and the latency period between infection and the onset of AIDS in
data where both the events of infection and AIDS are not directly obs
erved. The methods use self-consistency equations that are more easily
and quickly solvable than the nonparametric estimators proposed by De
Gruttola and Lagakos (1989, Biometrics 45, 1-11). The techniques are
illustrated with data on hemophiliacs who became infected through cont
amination of the blood factor they were given to control their hemophi
lia.
