Unevenly spaced time series
Weban unevenly spaced time series by means of the Lomb–Scargle Fourier transform depends on the distribution of the samplingtimes in the interval [t 1,t N] (Lomb, 1976; Scargle, 1982). For some arbitrary distribution of samplingtimes the lack of an analytical solution for the deviation prevents a direct Web11 Apr 2024 · NCVO Governance Forum.

WebA Python cross correlation command line tool for unevenly sampled time series. Requirements Python 2.7, 3.4, 3.5 Numpy Scipy Matplotlib Introduction The Discrete Correlation Function (DCF) was developed by Edelson and Krolik, 1988, ApJ, 333, 646 for use on unevenly sampled and/or gapped data. In statistics, signal processing, and econometrics, an unevenly (or unequally or irregularly) spaced time series is a sequence of observation time and value pairs (tn, Xn) in which the spacing of observation times is not constant.
