Estimating Tree-Structured Covariance Matrices via Mixed-Integer Programming
We present a novel method for estimating tree-structured covariance matrices directly from observed continuous data. Specifically, we estimate a covariance matrix from observations of p continuous random variables encoding a stochastic process over a tree with p leaves. A representation of these cla...
