Define a Restricted Cubic Spline Survival Distribution

Description

Define a restricted cubic spline parametric survival distribution.

Usage

define_surv_spline(scale = c("hazard", "odds", "normal"), ...)

Arguments

scale	"hazard", "odds", or "normal", as described in flexsurvspline. With the default of no knots in addition to the boundaries, these models reduce to the Weibull, log-logistic and log-normal respectively. The scale must be common to all times.
...	Additional distribution parameters (see respective distribution help pages).

Value

A surv_dist object.

Examples

define_surv_spline(
  scale = "hazard", 
  gamma = c(-18.3122, 2.7511, 0.2292), 
  knots=c(4.276666, 6.470800, 7.806289)
)
define_surv_spline(
  scale = "odds", 
  gamma = c(-18.5809, 2.7973, 0.2035), 
  knots=c(4.276666, 6.470800, 7.806289)
)
