Abstract |
Existing statistical methodology has been adapted to give additional insight into the data on pine-growth reduction in the Southeast as presented by Sheffield et al. (1985). Specifically the generation of confidence intervals for the percentage growth reduction is illustrated. The probability integral transformation and cumulative sum techniques are employed as a meta-analytic approach to testing the significance of the growth reduction. While these methods are suggested as a means of obtaining a quantitative overview of these particular data, the potential for wider application exists. It is also shown how the observed pattern of reduction and most, if not all, of its magnitude can be explained by a simple conceptual model for hardwood competition. Verification of the approach is, however, not possible with the data as provided by Sheffield et al. (Copyright (c) 1990 by the Society of American Foresters.) |
