Random variable

A function that assigns a real number to each and every possible outcome of a random experiment.

On the assumption that the stochastic variables follow Brownian motion, the maximization results in an intuitively satisfying result where the optimum net worth is determined by the maximum distance between the growth of net worth (a linear function of the level of debt) and the mean risk (a convex function of the level of debt), which is shown graphically in Figure 4.
