WebbIn this paper, a Partial Least-Squares (PLS) regression approach is developed to study relationships between land use and its influencing factors through a case study of the Suzhou-Wuxi-Changzhou region in China. Multicollinearity exists in the dataset and the number of variables is high compared to the number of observations. WebbPartial least squares (PLS) works by extracting one factor at a time. Let X=X 0 be the centered and scaled matrix of predictors and Y=Y 0 the centered and scaled matrix of response values. The PLS method starts with a linear combination t = X 0 w of the predictors, where t is called a score vector and w is its associated weight vector.

WebbThe factor loadings show how the PLS factors are constructed from the centered and scaled predictors. For spectral calibration, it is useful to plot the loadings against the frequency. In many cases, the physical meanings that can be attached to factor loadings help to validate the scientific interpretation of the PLS model. Webb28 okt. 2001 · PLS-regression (PLSR) is the PLS approach in its simplest, and in chemistry and technology, most used form (two-block predictive PLS). PLSR is a method for relating two data matrices, X and Y, by a linear multivariate model, but goes beyond traditional regression in that it models also the structure of X and Y.PLSR derives its usefulness …
