Simulating enrollment dates — enrollment • bayesCT

This function simulates enrollment dates using either Poisson distribution

enrollment(param, N_total, time = NULL)

Arguments

param	vector. Lambda values for Poisson distribution.
N_total	integer. Value of total sample size.
time	vector. Knots (of `length(param)` - 1) indicating end of time when a specific lambda is used.

Value

A vector of enrollment times (from time of first patient enrollment) in days.

Examples

enrollment(param = c(0.003, 0.7), 100, time = 10)
