The deviation between the May 1 stocks estimate and the final estimate is expressed as a percentage of the final estimate. The average of squared percentage deviations for the latest 20-year period is computed. The square root of the average becomes statistically the "Root Mean Square Error." Probability statements can be made concerning expected differences in the current estimate relative to the final end-of-season estimate, assuming that factors affecting this year's estimate are not different from those influencing recent years. The "Root Mean Square Error" for the May 1 stocks estimate is 6.5 percent. This means that chances are 2 out of 3 that the current estimate of 87.0 million cwt will not be above or below the final estimate by more than 6.5 percent or approximately 5.7 million cwt. Chances are 9 out of 10 (90 percent confidence level) that the difference will not exceed 11.3 percent or approximately 9.8 million cwt. The 10-year (1994-2003) record of differences between the May 1 stocks estimates and the final estimates averaged 3.2 million cwt, ranging from 9.9 million cwt above the final to 6.1 million cwt below the final. During the 10-year period, the May 1 estimate has been below the final estimate 7 years and above 3 years.
