Description: Implements the Cross-Entropy (CE) method, which is a model based stochastic optimization technique to estimate both the number and their corresponding locations of break-points in continuous and discrete measurements (Priyadarshana and Sofronov (2015), Priyadarshana and Sofronov (2012a), Priyadarshana and Sofronov (2012b)).

person("University Hospital of Zurich, Dep. Gastroenterology", role = c("fnd", "dtc"))
Description: Reads several formats of 13C data (IRIS/Wagner, BreathID) and CSV.
Creates artificial sample data for testing.
Fits Maes/Ghoos, Bluck-Coward self-correcting formula using 'nls', 'nlme'.
This package contains a refactored subset of github package
'dmenne/d13cbreath' without database and display functions. Methods to
fit breath test curves with Bayesian Stan methods are refactored to
github package 'dmenne/breathteststan'. For a Shiny GUI, see
