Abstract

A problem in the earth sciences is to reduce a sequence of observation vectors X₁, X₂, ..., X_N to a set of internally homogeneous segments or zones. This paper uses the model that the observation vectors in the ith zone are a random sample from the multivariate normal N(ξ_i, Σ_i) distribution. It is demonstrated that the maximum likelihood estimates of the boundaries between zones may be determined by dynamic programming, and a FORTRAN algorithm to perform this estimation is given.
