main.R: apply different hybrid control methods (HY-MEM, HY-MAP, HY-rMAP) to simulated trials
main summary.R: calibrate each design by controling FWER at a target level, assuming internal and external data is consistant. it produces the familiy-wise power and type I error rate of each design under a varying level of internal-external data conflict in different scenarios
simulate.R: simulate internal data and external data
get.design.R: find the design parameters of each design under a prespecified FWER level
mem functions.R: implement the MEM approach and find a suitable choice for delta (find.mem.prior)
