Detection of Weak Periodic Signals from Irregularly Spaced Observations
Jorg Pfleiderer, Martin Mössner · International Astronomical Union Colloquium · 1995
Abstract We perform time series analysis on irregularly spaced data with large gaps. Our algorithm is based on multidimensional nonlinear optimisation. Particular emphasis is given to the selection and deletion of frequencies. The final result is checked by various statistical tests.
