Let (Ω,𝓐,P) be a probability space and let τ: ℝ × Ω → ℝ be strictly increasing and continuous with respect to the first variable, and 𝓐-measurable with respect to the second variable. We obtain a partial characterization and a uniqueness-type result for solutions of the general linear equation
$F(x) = ∫_{Ω} F(τ(x,ω))P(dω)$
in the class of probability distribution functions.
