Simulate survival data for multiple databases
simulatePopulations(settings = createSimulationSettings())

An object of type |
A object of class simulation
, which is a list of populations, each a data frame with columns
rowId
, stratumId
, x
, time
, and y
.
settings <- createSimulationSettings(nSites = 1, hazardRatio = 2)
populations <- simulatePopulations(settings)
# Fit a Cox regression for the simulated data site:
cyclopsData <- Cyclops::createCyclopsData(Surv(time, y) ~ x + strata(stratumId),
data = populations[[1]],
modelType = "cox"
)
cyclopsFit <- Cyclops::fitCyclopsModel(cyclopsData)
coef(cyclopsFit)
# (Estimates in this example will vary due to the random simulation)
