text: We study multivariate normal models that are described by linear constraints
on the inverse of the covariance matrix. Maximum likelihood estimation for such
models leads to the problem of maximizing the determinant function over a spectrahedron,
and to the problem of characterizing the image of the positive definite cone under
an arbitrary linear projection. These problems at the interface of statistics
and optimization are here examined from the perspective of convex algebraic geometry.
