Resolution of Source Contributions to Environmental Samples. Technical Progress Report, July 1, 1985-June 30, 1986

摘要

During the current year, we have continued the study of two methods for identifying the sources of environmental samples and apportioning the mass contributions of those sources. The primary focus has been in the source apportionment of ambient aerosol mass. The first area of interest has been the examination of advanced regression diagnostics and linear programming methods. The use of a full range of regression diagnostics including a variety of residuals analyses have been explored. We have also developed a better understanding of linear programming approaches and source selection methods so that better estimates of the source contributions can be calculated as well as better estimates of the real uncertainties in those estimates.
