Weighted analysis methods for mapped plot forest inventory data: Tables, regressions, maps and graphs

Weighted estimation methods for analysis of mapped plot forest inventory data are discussed. The appropriate weighting scheme can vary depending on the type of analysis and graphical display. Both statistical issues and user expectations need to be considered in these methods. A weighting scheme is proposed that balances statistical considerations and the logical expectations of users. The methods described here are being used in an online forest carbon estimation tool. Example applications are presented to demonstrate the methods. (C) 2010 Elsevier B.V. All rights reserved.
