Value
View source: R/fonctions_sujets.R
Description
This function will provide the total sample size of your planned cost-effectiveness study.
The optimal sample size of your planned cost-effectiveness study is reached when EVPIn (a vector calculated by the evpi_decrease object) is less or equal to (step_ref + step_exp)*cost_indiv
Usage
1
sample_size(object_evpi_decrease, cost_indiv)
Arguments
object_evpi_decrease
: evpi_decrease object. See create_object_evpi_decrease
cost_indiv
: cost of an additional inclusion in your planned cost-effectiveness study.
Value
A dataframe containing three vectors : N, N_exp, N_ref, the total number of subjects of your planned cost-effectiveness study, in the experimental group and in the reference group respectively.
