ABSTRACT="Maximum Likelihood estimates and their asymptotic distribution
are obtained for the transition probabilities on a Markov chain of
arbitrary order when there are repeated observations of the chain.
Likelihood ratio tests, xý-tests and other tests of seva-ral hypothesis
are considered. The statistical analysis in the case of a single
observation of a long chain is also dicussed.",

ABSTRACT="The removal of the mean from a stochastic process may be
regarded as a particular case of the elimination of a polynomial trend. 
The object of this paper is to determine how the removal of this trend
affects both the biases and the covariances of theestimators of the
covariances and of the autocorrelation coefficients; it is not assumed
that the process is necessarily Gaussian.",

also studied.",

proceed to a second (multiple-counter) queue after having been pocessed
at a first (multiple-counter) queue. For reasons of expediency we
restrict ourselves to the case of unsaturated queues in ``equilibrium'',
that is, to stationary statistics. The main results are for the case of
exponential service time, where it turns out that, contrary to a-priori
intuition, the situation is surprising",
