Book excerpt: Excerpt from Computing Average Log Values for Timber Appraisals Using Ibm 650 or Univac Solid State 80 Computers A necessary part of most timber appraisals is to determine the relationship between average Value per board feet and scaling dia meter for logs of known log grades. In the past, this average value has been determined by first computing the values per board feet for individual logs of known diameter and log grade and then relating these values, usually graphically, to any log diameter. The plotted data ordinarily vary a good deal. Therefore, to prepare tables of average log value, it is necessary to eliminate the variation by fitting smooth curves to the data and determining values directly from.the curves.
