Abstract :A powerful method for the analysis of time series has been developed by Kendail insert ignore into journalissuearticles values(1);. In their careful statistical analysis of the light curve of p Ccphei, Ashbrooh, Duncombe and van Woer- kom insert ignore into journalissuearticles values(2); have succesfully applied his autocorrelation analysis. Ashbrook, Duncombe and van Woerkoro found the light curve of P Cephei to result from stochastic rather than harmonic processes whii« it could be represented by a second order auto-regressive chaİB. At the same time from the method apphed by them, they were able to show that thefour periods, which on the hasis of a Schuster periodogram had been assigaed to p Cephei, were illusory.
