Fitting curves to cyclic data
W. B. Langbein
1955, Open-File Report 55-91
A common problem in hydrology is to fit a smooth curve to cyclic or periodic data, either to define the most probable values of the data or to test some principle that one wishes to demonstrate. This study treats of those problems where the length or period of the cycle...
