%description
Bayesian methods for predicting the calendar time at which a target number
of events is reached in clinical trials. The methodology applies to both
blinded and unblinded settings and jointly models enrollment, event-time,
and censoring processes. The package provides tools for trial data
simulation, model fitting using 'Stan' via the 'rstan' interface, and
event time prediction under a wide range of trial designs, including
varying sample sizes, enrollment patterns, treatment effects, and event or
censoring time distributions. The package is intended to support interim
monitoring, operational planning, and decision-making in clinical trial
development. Methods are described in Fu et al. (2025)
<doi:10.1002/sim.70310>.
