On the Distribution Function of the Complexity of Finite Sequences
  Investigations of complexity of sequences lead to important applications such as effective data compression, testing of randomness, discriminating between information sources and many others. In this paper we establish formulas describing the distribution functions of random variables representing the complexity of finite sequences introduced by Lempel and Ziv in 1976. We show that the distribution functions depend in an affine way on the probabilities of the so called "exact" sequences.
