Evaluations based on the Q or R mode are also needed in connection with other multivariate methods. In general, the technique is called R analysis when the relationship among p features determined by n observations is of interest. Q analysis examines the relationship among n objects characterized by p variables. For the most frequently used approach in FA, the interpretation of the loadings can be denoted as R analysis and, as seen as follows, the evaluation of the scores as Q analysis. [Pg.151]

Denote the matrix of the eigenvectors that were determined from the correlation matrix by Q analysis, Uq, by U, and the eigenvector matrix of R analysis, R, by V, then decomposition of the matrix X by means of SVD reveals [Pg.158]

All product analysis of effluent gas streams was performed by on-line gas chromatography. Two different gas chromatographs were employed, each with heated sample valve connected to the reactor effluent stream. Analysis of light (Ci-C5) hydrocarbons and dimethyl ether was performed by a Varian 1400 GC equipped with flame ionization detector. Separation of the products was accomplished by a 20 column (1/8" O.D.) packed with Porapak Q. Analysis of hydrocarbons in the C5 to [Pg.77]
