histogram/test/utility_wald_interval_test.cpp
Jay Gohil 10c19df918
Add fraction accumulator (for calculating efficiencies, etc) (#361)
* Added fraction accumulator
* Added binomial proportion interval computers: Wald, Wilson Score, Clopper Pearson, Jeffreys
* Width of intervals for all classes can be set via deviation or confidence_level
* Support valarray in histogram::fill
* Add fraction and count to user guide
