Plot bias — plot_bias • psborrow

Plot bias for each prior distribution according to selected simulation parameters

Usage

plot_bias(dt, HR = 1, driftHR = 1, pred = "none")

dt: a data.frame containing summary statistics for the posterior samples from each simulation generated with get_summary.
HR: pre-specified HR between treatment and control arm in the internal trial for which the bias should be plotted. Must be within unique(dt$HR).
driftHR: pre-specified HR between external control arm and internal control arm for which the bias should be plotted. Must be within unique(dt$driftHR).
pred: predictors to use when fitting exponential distribution in MCMC for which the bias should be plotted. Must be within unique(dt$pred).

a bar plot of class ggplot containing the bias for each prior distribution.
