Abstract

Univariate approaches to ratio of means calibration of phase I variables in two-phased forest, inventories may lead to suboptimal properties when calibrated results are used in a multivariate context, as exemplified by a growth model. Application of bootstrap resampling techniques makes it possible to find a multivariate set of ratios of means with optimum properties in terms of global performance criteria.
