Time-Series Power Spectrum Analysis of Performance in Free Response Anomalous Cognition Experiments
نویسنده
چکیده
We analyze a database of 3,325 free response anomalous cognition experiments, using procedures recently used in an analysis of a catalog of UFO events. A histogram analysis shows evidence of a significant annual modulation in the success rate, but no significant evidence for modulations associated with time of day or local sidereal time (LST). The salient feature of a power spectrum formed by the Lomb-Scargle procedure is a peak at a frequency very close to twice the lunar synodic frequency. The probability that this feature occurs by chance is estimated to be 0.03%. A running-wave analysis indicates that this is an astronomical effect rather than a spurious property of the database. We also find a peak in the power spectrum with a period of one year. This could be associated with an LST effect, but the running-wave test, which is designed to distinguish between a real LST effect and a spurious LST effect, does not support this interpretation.

The present paper introduces the Bayesian spectral analysis as a powerful and efficient method for spectral analysis of photometric time series. For this purpose, Bayesian spectral analysis has programmed in Matlab software for XZ Dra photometric time series which is non-uniform with large gaps and the power spectrum of this analysis has compared with the power spectrum which obtained from the ...
متن کاملA new approach to detect Life threatening cardiac arrhythmias using Sequential spectrum of Electrocardiogram signals
This study evaluates the discriminative power of sequential spectrum analysis of the short-term electrocardiogram (ECG) time series in separating normal and subjects with life threatening arrhythmias like, ventricular tachycardia/fibrillation (VT/VF). The raw ECG time series is transformed into a series of binary symbols and the binary occupancy or relative distribution of mono-sequences (i.e. ...

Fractal analyzing of continuous processes have recently emerged in literatures in various domains. Existence of long memory in many processes including financial time series have been evidenced via different methodologies in many literatures in past decade, which has inspired many recent literatures on quantifying the fractional Brownian motion (fBm) characteristics of financial time series. Th...

In this paper, we propose a new residual analysis method using Fourier series transform into fuzzy time series model for improving the forecasting performance. This hybrid model takes advantage of the high predictable power of fuzzy time series model and Fourier series transform to fit the estimated residuals into frequency spectra, select the low-frequency terms, filter out high-frequency term...
