Description Usage Arguments Value
Subjects are accrued according to the c.d.f
G(t)=t^k/B^k
where k
is a parameter,
t
is the time and B
is the recruitment period.
See the predict from data vignette for further details
1 2 | Generate.Accrual(start.date, end.date, k, deterministic = FALSE,
rec.start.date = NULL)
|
start.date |
The start of the subject accrual period |
end.date |
The date the last subject is accrued so |
k |
The non-uniformity accrual parameter |
deterministic |
Logical, if FALSE then the recruitment times
are non-stochastically chosen so that their cumulative distribution function is |
rec.start.date |
If this argument is used the subjects are still recruited between
start.date and end.date but they follow the cdf |
