Do Leading Indicators Lead Peaks More Than Troughs?∗
We develop a formal statistical approach to investigate the possibility that leading indicator variables have different lead times at business cycle peaks and troughs. For this purpose, we propose a novel Markov switching vector autoregressive model, where economic growth and leading indicators share a common Markov process determining the state, but such that their cycles are non-synchronous w...
متن کاملA model of the perceptual asymmetry between peaks and troughs of frequency modulation
Pitch discrimination at peaks of frequency modulation is better than at troughs @L. Demany and K. I. McAnally, J. Acoust. Soc. Am. 96, 706–715 ~1989!#. A similar asymmetry emerges within a time-domain pitch perception model based on autocorrelation. The model requires the following assumptions: ~a! The neural discharge patterns must be temporally sharpened to a single narrow pulse per period ~p...
متن کاملPeaks and Troughs in Helioseismology: The Power Spectrum of Solar Oscillations
I present a matched-wave asymptotic analysis of the driving of solar oscillations by a general localised source. The analysis provides a simple mathematical description of the asymmetric peaks in the power spectrum in terms of the relative locations of eigenmodes and troughs in the spectral response. It is suggested that the difference in measured phase function between the modes and the trough...
متن کاملThe peaks and troughs of wave energy, the dreams and the reality.
A residential Discussion Meeting on ‘The peaks and troughs of wave energy: the dreams and the reality’, organized by R. C. T. Rainey, J. R. Chaplin and myself, was held at the Kavli Royal Society International Centre on 13–15 October 2010. The programme and a verbatim record of the meeting and discussions are available on the Royal Society’s website (talks can be downloaded from http://royalsoc...
متن کاملA model of the perceptual asymmetry between peaks and troughs of frequency modulation.
Pitch discrimination at peaks of frequency modulation is better than at troughs [L. Demany and K. I. McAnally, J. Acoust. Soc. Am. 96, 706-715 (1989)]. A similar asymmetry emerges within a time-domain pitch perception model based on autocorrelation. The model requires the following assumptions: (a) The neural discharge patterns must be temporally sharpened to a single narrow pulse per period (p...
