Partial least squares (PLS) regression is a statistical method that bears some relation to principal components regression and is a reduced rank regression [1]; instead of finding hyperplanes of maximum variance between the response and independent variables, it finds a linear regression model by projecting the predicted variables and the ...

2020年11月17日 · A technique that is related to PCR is known as partial least squares. Similar to PCR, partial least squares calculates M linear combinations (known as “PLS components”) of the original p predictor variables and uses the method of least squares to fit a linear regression model using the PLS components as predictors.

2024年1月19日 · Partial least squares regression (PLS regression) is a statistical technique that shares similarities with principal components regression. Instead of identifying hyperplanes of maximum variance between the response and independent variables, PLS regression constructs a linear regression model by projecting both the predicted and observable ...

Partial least squares(PLS) is a method for construct- ing predictive models when the factors are many and highly collinear. Note that the emphasis is on pre- dicting the responses and not necessarily on trying to understand the underlying relationship between the variables.

Pls regression is a recent technique that generalizes and combines features from principal component analysis and multiple regression. It is particularly useful when we need to predict a set of dependent variables from a (very) large set of independent variables (i.e., predictors).

2025年1月27日 · Partial least squares regression is a powerful method for analyzing complex relationships among multiple variables, particularly in high-dimensional data sets. You can apply it to a variety of fields, such as business, science, bioinformatics and anthropology.

Partial least-squares (PLS) regression is a technique used with data that contain correlated predictor variables. This technique constructs new predictor variables, known as components, as linear combinations of the original predictor variables.

Partial least squares and the closely related principal component regression technique are both designed to handle the case of a large number of correlated independent variables, which is common in chemometrics.

Partial Least Squares Regression (PLS) is a machine learning technique, combining the advantages of integrating principal component analysis, typical correlation analysis, and linear regression analysis.
