as a linear combination Xi·B of the q columns of X, plus some mean-zero random error Ui·. Perhaps fewer than q terms would suffice to predict Y adequately or, more realistically, perhaps some number m < q of linear combinations of the columns ofX would suffice. That is the essence of Factor Analysis, a method proposed in 1904 by psychologist Charles Spearman in his effort to show that all measu...

the paper presents a multi-factor decision-making approach for prioritizing failure modes as an alternative to traditional approach of failure mode and effect analysis (fmea). the approach is based on the ‘technique for order preference by similarity to ideal solution’ (topsis). the priority ranking is formulated on the basis of six parameters (failure occurrence, non-detection, maintainability...
