  Fractal structure of charged particle distributions in the pseudorapidity and
transverse momentum in central C-Cu collisions at 4.5A GeV/c is studied by
means of intermittency approach and multifractal analysis. The modifications to
take into account statistical bias are applied. Intermittency study in the
pseudorapidity phase space indicates a non-thermal phase transition and
different regimes of multiparticle production. Multifractality is observed
within the both methods applied. The interrelation of the methods using the
effective average multiplicity approach is studied. The findings support the
idea of statistical significance of influence of finite multiplicities. In the
transverse momentum spectrum no dynamical fluctuations are found.
