英文文献作者：Sarassoro, Gboroton F.,Hudson, Michael A.,Leuthold, Raymond M.
英文文献摘要：
The distribution of day-to-day price changes for wheat, soybean, and live cattle futures contracts was examined for the period from January 1973 through December 1982. The results demonstrate a move toward independence and normality, suggesting option pricing formulae which assume normality may provide accurate representations of option values.
