Abstract
Let X be a random variable with distribution P on a measurable space χ. A function q*(x) is log-optimum in a convex family 𝒬 of nonnegative measurable functions on χ if it attains the maximum growth exponent W𝒬(X)=supq(xin𝒬)E{log q(x)}. The analysis of random variable with joint distributions generalizes to the setting of stationary processes and log-optimum selections in multiplicative sequences of convex families
