The raise estimators are used to reduce collinearity in linear regression models by raising a column in the experimental data matrix, which may be nearly linear with the other columns, while keeping the basic OL
The problem of ill-conditioning in generalized linear regression is investigated. Besides collinearity among the explanatory variables, we define another type of ill-conditioning, namely ML-collinearity, which has similar detrimental effects on the covariance matrix, e.g. inflation of some of the ...
In case of multiple linear regressions, estimated parameters values and some statistical tests are influenced by collinearity between explanatory variables. In fact, collinearity acts as a noise which distorts the signal (proper parameter values). This influence is emphasized by the coefficients of ...

They are known as statistically collinear if one of them is approximately a linear combination of other variables. In the case of a regression model where the explanatory variables are strongly correlated to each other, we say that there is collinearity (or multicollinearity) between the explanatory...

In this case, the rank of XTX is less than K, and XTX is singular and cannot be inverted; hence, it is not possible to calculate the OLS estimates of the regression coefficients with Equation (7). Usually (e.g., near-infrared (NIR) spectra), the x-variables are neither completely ...
In particular, this study considers the VinodâUllah ridge-type estimators at the first and/or second stage of 2SLS. Ridge regression in the second stage only of 2SLS but not the first stage only, seems to be a practical alternative to 2SLS, especially in situations of strong ...
