An important source of risk in agricultural production is the variability to crop yields reflecting irregularly changing weather. This variability may be described as a stochastic process that has a function of density. Analyses of historical data on crop yields reveal that the function of density changed from right-skewed to left-skewed, along with increasing mean yields. A fairly good approximation of the probability distribution for actual yields may be obtained using the log-normal distribution with an inverted abscissa
