A NEW POWERFUL TRANSFORMATION FOR MAXIMUM-LIKELIHOOD COMMON FACTOR-ANALYSIS (MLCFA)

A new transformation technique for maximum likelihood common factor an alysis (MLCFA) is proposed as an alternative method for the traditiona l target transformations. The so-called multiple region transformation (MRT) makes no use of spectral reference libraries or target vectors, but computes the real solution analytically. Both techniques, MLCFA a nd MRT, are incorporated in a factor analysis software package, called Factor Soft(C) (FS).(1) The factor analysis software FS has been appl ied in combination with AES to study the reaction products formed at t he interface of natural rubber vulcanized on a thin brass layer under specific conditions.
