Statistical tools for determining appropriate selection of regression models for analysis of environmental fate datasets
Aldworth, W., & Jackson, SH. (2008). Statistical tools for determining appropriate selection of regression models for analysis of environmental fate datasets. Pest Management Science, 64(5), 536-543.
BACKGROUND: In the NAFTA regulatory community, a currently consistent methodology used to estimate dissipation times for environmental fate data is not applied.RESULTS: This work demonstrates through a case study that the inappropriate use of pseudo-first-order regression models can result in inaccurate estimates of soil degradation rates, and it proposes some statistical tools that can be used to identify an appropriate statistical model to fit a particular environmental fate dataset. Diagnostic procedures have been proposed to identify the appropriate scale, and statistical testing procedures have been proposed to select the appropriate model within that scale.CONCLUSION: Results from this work demonstrate that, unless the proposed diagnostic and statistical procedures are used, inaccurate estimates of dissipation times may result.
