Implement stratified sample size method from Bernstein and Lagakos #81

Closed nanxstats closed 1 year ago

nanxstats commented 1 year ago

From Keaven:

The Bernstein and Lagakos method[^1] can be added to gsDesign as an alternate stratified sample size method for comparison.

Nan: The original paper gives a FORTRAN routine. I found an R implementation.

Will do this in gsDesign2 instead. See https://github.com/Merck/gsDesign2/issues/205.
