Abstract
A comparison is made of three statistical methods of determining the autocorrelation coefficients and correlation length in a time-data series obtained by a computer simulation. Three points of state were chosen where the fluctuations and correlations play different roles: in the liquid, in the solid near melting, and in the melting zone. Taking account of the physical meaning of the results, it is found that there is always a limiting value of the lag at which the series must be cut off.
