Two-dimensional Markov spectrum estimates need not exist

Because a function of two variables which is positive definite over a rectangle may not have a positive definite extension to the entire plane, two-dimensional Markov spectrum estimates based on estimated autocorrelation data do not always exist. The ramifications of this fact are discussed.
