Multiple linear regression
I am reading the articles about the pseudoinverse and wondering about what is the difference between that and multiple linear regression. In another word, if I have a same set of linear equations, using the pseudoinverse method or linear regression, should I get same solution? Thanks. Simonliang (talk) 00:55, 29 September 2008 (UTC)
Construction formulae: unhelpful?
I'm thinking of changing or removing the construction formulae for the left and right inverses, for three reasons:
- The formulae only apply when the matrix has full rank;
- When is poorly conditioned, the formulae suffer from numerical issues;
- The formulae, if they apply at all and give sufficiently accurate results, give only the Moore-Penrose pseudo-inverse, and do not constitute general formulae for the construction of generalized inverses (which are the subject of the article).
Any comments before I press on with my edits? Cooperised (talk) 22:35, 3 June 2013 (UTC)
