This function calculates the minimum sample size of each partition when the number of subgroups is given.
1 | count.mindat(formula, data, part = 10)
|
formula |
a Formula object with a response on the left hand side of the '~' operator, and the covariate terms on the right side. The response has to be a survival object with survival time and censoring status in the Surv function. For more details, see Formula page. |
data |
a data frame with variables used in formula. It needs at least three variables including survival time, censoring status, and a covariate. Multivariate covariates can be supported with "+" sign. |
part |
a numeric object to determine the number of subgroups we want to split. |
1 2 3 4 | data(toy)
count.mindat(Surv(time,staus) ~ meta, data = toy, part =5)
count.mindat(Surv(time,staus) ~ meta, data = toy, part =10)
count.mindat(Surv(time,staus) ~ meta, data = toy)
