This is the main function in the blendR package. Two survival curves are supplied and blended according to the blending distribution characterised by the blending interval and the beta distribution parameters.
Usage
blendsurv(
obs_Surv,
ext_Surv,
blend_interv,
beta_params = list(alpha = 3, beta = 3),
times = NULL,
nsim = 100
)Arguments
- obs_Surv, ext_Surv
Observed and external data survival curves. These can come from survHE, INLA or flexsurv fits.
- blend_interv
Maximum and minimum values for the blending interval.
- beta_params
coefficients of a beta distribution
- times
A vector of times for which the survival curves are to be computed; optional
- nsim
The number of simulations from the distribution of the survival curves; default 100
