weightPredict

Extracts cumulative hazard estimates for each individual. Each
individual receives a weight process evaluated at pre-specified time points.
The weight process is estimated as a cumulative product involving estimated
cumulative hazard increments, and a hazard ratio estimated using a smoothing
parameter <code>b</code>.

Estimates continuous time weights for performing causal survival
analysis. For instance, weighted Nelson-Aalen or Kaplan-Meier
estimates can be given a causal interpretation. See Ryalen, Stensrud,
and Røysland (2019) <doi:10.1007/s10985-019-09468-y> and Ryalen (2019)
<https://www.duo.uio.no/handle/10852/70353>
for theory and examples.
