K-BEtest is a well known program for bioequivalence test using a 2×2 design. Lee et al.(1998) and Park et al.(1999) suggested a 3×3 and 3×2 design, and also discussed their benefits. We developed a computer program, called BioEquiv, which can analyze some complex experimental designs such as, 3×3 design and 3×2 design including a standard 2×2 design. This program is a user-friendly one and overcomes the disadvantages of K-BEtest?. The detailed statistical formula and structure of BioEquiv are presented with some examples. The comparison between K-BEtest? and BioEquiv are given with actual data analysis. BioEquiv is able to present a table of ANOVA test over some complex experimental designs. Moreover K-BEtest? and BioEquiv draw the same result when data consists of 2×2 design.
