New distribution density functions were proposed by using the finite difference method to express the frequency distribution of individual plant sizes in a stand. The finite differences were computed for plant weights arranged in descending order. The finite difference equation of the first order using constant coefficients resulted in distribution density functions of a uniform and reciprocal type. One type of Pearson's VIIth type distribution density function was obtained from a difference equation of the second order to simulate frequency distributions with a maximum frequency value. In addition, a more general function with wider applicability, which enabled the simulation of asymmetric (with respect to the mode of frequency) and even extremely skew distributions, was derived.
