Language: en-GB to DESCRIPTION.plot_rcp1armRMST() and
plot_rcp1armMilestoneSurvival() in \donttest{}.Calculation functions â each supports approach = "formula" (closed-form or semi-analytical) and approach = "simulation" (Monte Carlo), and returns both Method 1 and Method 2 RCP:
rcp1armContinuous(): Continuous endpoint. Method 1 uses normal approximation via two-block decomposition; Method 2 uses the product of independent regional probabilities.rcp1armBinary(): Binary endpoint. Method 1 uses exact enumeration of the binomial joint distribution; Method 2 uses the product of independent binomial tail probabilities.rcp1armCount(): Count endpoint (negative binomial model). Provides RCP on both the log-RR scale and the linear-RR scale via the reproducibility property of the negative binomial distribution.rcp1armHazardRatio(): Time-to-event endpoint (hazard ratio). Closed-form solution based on normal approximation for log(HR) and the delta method for the linear-HR scale (Hayashi and Itoh 2018). Supports accrual period, follow-up period, and exponential dropout.rcp1armMilestoneSurvival(): Milestone survival endpoint. Variance of the Kaplan-Meier estimator derived from Greenwood's formula (Tang 2022). Returns "closed-form" when t_eval <= t_f and "numerical-integration" otherwise.rcp1armRMST(): Restricted mean survival time (RMST) endpoint. Variance formula via integration of the squared survival difference. Returns "closed-form" when tau_star <= t_f and "numerical-integration" otherwise.Plot functions â each generates a faceted ggplot2 object overlaying formula and simulation results for Method 1 and Method 2 as a function of the regional allocation proportion fâ:
