The setting of this article is nonparametric algebraic statistics. We study moment varieties of conditionally independent mixture distributions on ℝ^n. These are the secant varieties of toric varieties that express independence in terms of univariate moments. Our results revolve around the dimensions and defining polynomials of these varieties.
