Quantitative Apportionment of Urban Aerosol Mass by Factor Analysis
… matter was developed. This procedure, called target transformation factor analysis (TTFA), requires no prior knowledge about the nature of the system under study. TTFA can determine the number of sources that are contributing to the system, determine the elemental composition of the particles …

Applicability of Factor Analysis to the Determination of Mineral Matter in Coal
… in coal was developed based on two types of factor analysis. Classical factor analysis was shown to identify trends in data sets that are indicative of the mineral phases and data errors. If a data error was identified by classical factor analysis, appropriate corrective action produced a …

Investigation of membrane permeation using ATR-FTIR spectroscopic imaging and multivariate target factor analysis
… scope and application of quantitative iterative target transformation factor analysis (QITTFA) which is a variant of target factor analysis (TFA) in the presence of instrumental noise and collinearity. The results show that QITTFA is robust in the presence of noise levels up to 35 %. The …
