In gset: Group Sequential Design in Equivalence Studies

Description

produces the 2-dimenisonal equivalence boundary plot for each stage in group sequential designs of equivalence studies

Usage

figureE(boundary, K, sm=3, lg=6)

Arguments

boundary	the equivalence boundaries c(L) and c(U) at each stage
K	number of stages/looks
sm	the short arm of the t(L) and t(U) axes; default is 3
lg	the short arm of the t(L) and t(U) axes; default is 6
