Information
has glosseng: In the analysis of time series, a correlogram, also known as an autocorrelation plot, is a plot of the sample autocorrelations r_h\, versus h\, (the time lags). If cross-correlation is used, it is called a cross-correlogram. The correlogram is a commonly-used tool for checking randomness in a data set. This randomness is ascertained by computing autocorrelations for data values at varying time lags. If random, such autocorrelations should be near zero for any and all time-lag separations. If non-random, then one or more of the autocorrelations will be significantly non-zero.

Meaning
German
has glossdeu: Ein Korrelogramm ist die graphische Darstellung der Autokorrelation einer Zeitreihe. Dazu werden die Korrelationskoeffizienten \rho_l\, gegen die Dauer der Zeitverschiebung l\, abgetragen. Überschreitet (unterschreitet) \rho_l\, die Obergrenze (Untergrenze) B\,, so wird die Nullhypothese, dass keine Autokorrelation vorliegt, mit einer Irrtumswahrscheinlichkeit von \alpha\, abgelehnt:
