Origin?

The origin for the algorithm stated here does not agree with that stated in the article additive model ... there isn't anything to say that there are different things called "backfitting algorithm". Melcombe (talk) 15:43, 22 September 2010 (UTC)[reply]

Definition of GAMs wrong

Given is the definition of AMs (not generalized). 160.83.30.197 (talk) 14:31, 16 November 2010 (UTC)[reply]

Algorithm: Pseudo Code wrong?

The last formula ${\hat {f_{j}}}\leftarrow {\hat {f_{j}}}-1/N\sum _{i=1}^{N}{\hat {f_{i}}}(x_{ij})$ in the pseudo code seems wrong or unnecessary to me. The index of ${\hat {f_{i}}}$ ist not self explaining and the idea behind the formula is not clear at all. I think one should delete this formula! 141.67.245.196 (talk) 10:15, 21 January 2011 (UTC)[reply]
