Extensions
In 2002 a new preprocessing method was published called orthogonal projections to latent structures (OPLS). In OPLS systematic variation in the X matrix not correlated to Y is removed. This improves the interpretability (but not the predictivity) of the PLS models. L-PLS extends PLS regression to 3 connected data blocks.

Famous quotes containing the word extensions:
“The psychological umbilical cord is more difficult to cut than the real one. We experience our children as extensions of ourselves, and we feel as though their behavior is an expression of something within us...instead of an expression of something in them. We see in our children our own reflection, and when we don’t like what we see, we feel angry at the reflection.”
—Elaine Heffner (20th century)
“If we focus exclusively on teaching our children to read, write, spell, and count in their first years of life, we turn our homes into extensions of school and turn bringing up a child into an exercise in curriculum development. We should be parents first and teachers of academic skills second.”
—Neil Kurshan (20th century)
