Problems encountered in multiple regression due to multicolinearity or missing data can be overcome by using PLS regression. Several versions of the PLS regression algorithm exist. In this paper, we present a new version of this algorithm which can be extended to generalized linear regression models such as ordinal or multinomial logistic regression, generalized linear models, and Cox regressio...

Regression is one of the most commonly used statistical techniques. However, testing regression systems a great challenge because absence test oracle in general. In this paper, we show that Metamorphic Testing an effective approach to multiple linear systems. doing so, identify intrinsic mathematical properties regression, and then propose 11 Relations be for testing. Their effectiveness examin...
