I have event time data for subjects with different categories (A, B, C etc.) yearly observed. To my understanding my data is both right and interval censored (?).
Subjects' category can change from year to year, e.g. A for years 0 to 2, than B from year 3 onwards for subject 1 etc. Each subject can be exposed to the "event" independent of its category. For time being I am not interested in transition effects.
Which estimators can be suggested for the 1 year failure probability per category?
