In econometrics, the Bry and Boschan routine finds statistical maxima and minima while using certain censoring rules and phase and cycle length constraints. [1], [2]

The OECD has composite leading indicators and turning points that are recession indicators with peak through the trough turning points chronologies determined by the rules in a computer routine (Bry and Boschan)[3]

The U.S. National Bureau of Economic Research (NBER) uses a computer routine (Bry and Boschan) and includes a Phase-Average Trend (PAT) detrending procedure. The turning point detection algorithm is decoupled from the de-trending procedure.[4]
