Given a fitted flexsurvmix model, return the Aalen-Johansen estimates of the
probability of occupying each state at a series of times covering the
observed data. State 1 represents not having experienced any of the
competing events, while state 2 and any further states correspond to having
experienced each of the competing events respectively. These estimates can
be compared with the fitted probabilities returned by
p_flexsurvmix to check the fit of a
Fitted model returned by
Data frame of alternative covariate values to check fit for. Only factor covariates are supported.
This is only supported for models with no covariates or models containing only factor covariates.
For models with factor covariates, the Aalen-Johansen estimates are computed
for the subsets of the data defined in
not supplied, then this function returns state occupancy probabilities for
all possible combinations of the factor levels.
The Aalen-Johansen estimates are computed using
survfit from the
survival package (Therneau
