Get the distribution of follow-up time
getFollowUpDistribution(population, quantiles = c(0, 0.25, 0.5, 0.75, 1))
A data frame describing the study population as created using the
createStudyPopulation function. This should at least have these
columns: treatment, timeAtRisk.
The quantiles of the population to compute minimum follow-up time for.
A data frame with per treatment group at each quantile the amount of follow-up time available.
Get the distribution of follow-up time as quantiles. Follow-up time is defined as time-at-risk, so not censored at the outcome.
