Abstract Over the past several years, a multivariate receptor model called Target Transformation Factor Analysis (TTFA) has been applied to various problems of environmental source resolution. In recent reports on the analysis of data sets with known structure, good results were obtained. In order to further test the TTFA approach, additional simulated data sets have been created with varying degrees of collinearity of the source profiles and normally distributed uncertainty. The effect of the collinearity is to restrict the number of resolvable sources. The analytical error affects the identification of the number of sources and development of accurate profiles.
