DM: Why is Singular Vector Decomposition for OLS?

[Krishnadas]

Hello,

Since SVD is used widely for OLS I guess it has clear advantages over
plain Inverse(X'X) X'Y.  Can anyone tell me about it?  Any good books
or references on the motivation for SVD and application of other 
matrix
decomposition in statistics?

Thanks.
