SafetyWindowConst
is the class for safety window length and it is used
when the gap
should be kept constant across cohorts (though it may vary
within a cohort).
Slots
gap
(
integer
)
a vector, the constant gap between patients.follow
(
count
)
how long to follow each patient. The period of time that each patient in the cohort needs to be followed before the next cohort opens.follow_min
(
count
)
minimum follow up. At least one patient in the cohort needs to be followed at the minimal follow up time.
Examples
# This is to have along the study constant parameters settings of safety window
# length, regardless of the cohort size.
my_win_len <- SafetyWindowConst(
gap = c(7, 5, 3),
follow = 7,
follow_min = 14
)
