Generate Patient Arrival Times

Calls the implementation from the common GeneratePoissonArrival example. Generates patient arrival times according to a Poisson process. When UserParam is supplied, its named rates dRate1, dRate2, and so on define a one-time-unit accrual ramp-up. Otherwise, PrdStart and AccrRate define the accrual periods and rates.

Usage

GeneratePoissonArrival(NumSub, NumPrd, PrdStart, AccrRate, UserParam = NULL)

Arguments

NumSub

Integer number of subjects to simulate.

NumPrd

Integer number of accrual periods.

PrdStart

Numeric vector containing the start time of each accrual period; the first value should be 0.

AccrRate

Numeric vector containing the accrual rate in each period.

UserParam

Optional list of user-defined rates named dRate1, dRate2, and so on.

Value

A list in the format required by the arrival integration point.
