Data on two-particle pseudorapidity and multiplicity correlations of charged particles for non single-diffractive $p\\bar{p}$ collisions at c.m. energies of 200, 546 and 900 GeV. Pseudorapidity correlations are interpreted in terms of a cluster model, which has been motivated by this and other experiments, require on average about two charged particles per cluster. The decay width of the clusters in pseudorapidity is approximately independent of multiplicity and of c.m. energy. The investigations of correlations in terms of pseudorapidity gaps confirm the picture of cluster production. The strength of forward--backward multiplicity correlations increases linearly with ins and depends strongly on position and size of the pseudorapidity gap separating the forward and backward interval. All our correlation studies can be understood in terms of a cluster model in which clusters contain on average about two charged particles, i.e. are of similar magnitude to earlier estimates from the ISR. Beam energy must be specified as analysis option "ENERGY" (200, 546 or 900 GeV) when rivet-merging samples.
