Calender year rates to Study Year Rates
Description
Given the cutpoints at which the hazard is to be constant, the values taken by the calender year rates and the calender time offset from the start of the trial at which randomization ended, this function converts to time on study rates, assuming uniform accrual.
Usage
CY2TOShaz(tcut, t.eor, m, verbose = FALSE)
Arguments
tcut |
Left hand endpoints of intervals on which time on study hazard is taken to be constant |
t.eor |
Time offsest from the beginning of the trial at which randomization ended |
m |
Annual calender time rates |
verbose |
do you want to see alot of debugging info–defaults to
|
Value
hazard = h, table = attr(obj., "tbl")
hazard |
time on study hazard values taken on intervals specified
by the argument |
table |
a table containg the observed and fitted values |
