Starting from a parametrized canonical expression for partition weights we investigate effects of uncorrelated stochastic fluctuations in the parameters. A special class of weights which are not affected by uncorrelated fluctuations is isolated and used as a reference for a systematic analysis of fluctuations. The technique is appled to partition weights obtained from a simple bond breaking percolation simulation. Strong evidence for the existence of uncorrelated fluctuations is obtained. The effects of fluctuations and of finite size effects on scaled factorial moments of the mass distribution are analyzed and discussed.
