  Citation × Citation Citation Abstract Copy Title: Statistical comparison of methods used in harvesting work studies Author: Oregon State University. Forest Research Laboratory, Miller, Mark E., Hossain, Mohammad M., Olsen, Eldon D. Work-study guidelines were developed using field data from thinning sites in the Oregon Cascade Range. Regression of detailed time study and shift-level data predicted harvesting production rates. Statistical analysis showed the relative difference in the discriminating power between shift-level studies versus detailed time studies. Indicator variables tested if there were significant differences between harvesting treatments. Confidence intervals demonstrated the improved effect of longer study lengths for both shift-level and detailed time studies.
