Did you know?
In statistics, ordinary least squares (OLS) is a type of linear least squares method for choosing the unknown parameters in a linear regression model (with fixed level-one effects of a linear function of a set of explanatory variables) by the principle of least squares: minimizing the sum of the squares of the differences between the observed dependent variable (values of the variable being observed) in the input dataset and the output of the (linear) function of the independent variable. NettetPartial Least Squares Regression Randall D. Tobias, SAS Institute Inc., Cary, NC Abstract Partial least squares is a popular method for soft modelling in industrial applications. This paper intro-duces the basic concepts and illustrates them with a chemometric example. An appendix describes the …

Least Square Regression may give predicted values beyond the range (0,1), but the analysis may still be useful for classification and hypothesis testing. Logistic regression models estimate probabilities of events as functions of …
