        Could you please send a complete program that demonstrates the problem? Thanks.
plz see roc_curve.hpp In this file accumulators.roc_curve is implimented, but I can not complie this by some err. May be defining accumulators inside accumulators causes some problem. roc_distribution.hpp is simple impl without using accumulators inside accumulators. It works. test program is test.cpp
