Letbe a complete stochastic basis, andXbe a semimartingale with predictable compensator. Consider a family of probability measures, whereis an index set,, and denote the likelihood ratio process by. Under some regularity conditions in terms of logarithm entropy and Hellinger processes, we prove thatconverges weakly to a Gaussian process inasfor each fixed.
