transform.hazards (version 0.1.1)
Transforms Cumulative Hazards to Parameter Specified by ODE
System
Description
Targets parameters that solve Ordinary Differential
Equations (ODEs) driven by a vector of cumulative hazard functions.
The package provides a method for estimating these parameters using
an estimator defined by a corresponding Stochastic Differential Equation
(SDE) system driven by cumulative hazard estimates. By providing cumulative
hazard estimates as input, the package gives estimates of the parameter as
output, along with pointwise (co)variances derived from an asymptotic
expression. Examples of parameters that can be targeted in this way include
the survival function, the restricted mean survival function, cumulative
incidence functions, among others; see Ryalen, Stensrud, and Røysland (2018)
, and further applications in
Stensrud, Røysland, and Ryalen (2019)
and Ryalen et al. (2021) .
