A mixture model for time to AIDS data with left truncation and an uncertain origin
Cyntha A. Struthers, Vernon Todd Farewell · Biometrika · 1989
The use of a mixture model to estimate the probability of developing AIDS after HIV infection and the distribution of incubation time is investigated. The possibility of left truncation and an uncertain time of infection is incorporated into the analysis. The efficiency losses associated with uncertain infection times are investigated. An example is given.
