Abstract

Over the recent years, Target Transformation Factor Analysis (TTFA) has been widely applied to various cases of environmental source resolution. As a multivariate receptor model, this form of factor analysis allows the determination of actual elemental source profiles. The analysis seeks to identify groups of samples with similar characteristics. Additionally, this technique identifies the correlation that exists between the data and utilizes them over the set of measured elements of different samples. This is practically accomplished on a matrix called correlation matrix. TTFA also permits the direct calculation of th
