The parameters were based on species-dependent equations linking Cited by:   [Timber] has a positive correlation with all other elements; thus, Cluster B is the components group connected to the adoption or non‐adoption of a timber structure.

Abstract. Graduation date: The Timber Resource Analysis System (TRAS) was the\ud timber supply projection model used in conjunction with\ud the Timber Assessment Market Model (TAMM) to predict\ud future U.S.

softwood timber harvests, inventories and\ud product prices in the RPA Timber. Updates and adds instructions for volume estimators, adds reference to FSH a, Timber Volume Estimators Handbook.

Adds definitions of statistical terms. Adds example calculations of cruise statistics. Updates direction for selecting cruise methods, timber File Size: 1MB. The model derived to explain historical timber sale prices, and to predict future sale revenue is as follows: (1) Revenue i = exp b 0 + b 1 ln T S V i + b 2 ln T P V i + b 3 ln S V P A i + b 4 ln S V P T i + b 5 ln P P I R i where Revenue i.

is revenue, in thousands of dollars, from timber sale i; TSV i. is total pine sawtimber volume Cited by: 2. The text provides literature surveys on relevant modeling issues and policy concerns, and demonstrates the application of the modeling system using a "base case" 50 year projection.

Types of yield prediction models. A yield prediction model uses the quantitative relationships between measured growth variables to predict yields of forest types, and is a tool that helps to schedule and regulate harvests at sustainable levels.

Two basic methods are available for their construction, diameter class (or stand table) projection. Books at Amazon. The Books homepage helps you explore Earth's Biggest Bookstore without ever leaving the comfort of your couch.
