This returns an estimate of the probability density for the time to each competing event, at a vector of times supplied by the user.
pdf_flexsurvmix(x, newdata = NULL, t = NULL)A data frame with each row giving the fitted density dens for
a combination of covariate values, time and competing event.
Fitted model object returned from flexsurvmix.
Data frame or list of covariate values. If omitted for a model with covariates, a default is used, defined by all combinations of factors if the only covariates in the model are factors, or all covariate values of zero if there are any non-factor covariates in the model.
Vector of times at which to evaluate the probability density
