:Both formulas have the same meaning, namely '''J'''^T'''Jq''' + λ'''q''' = −'''J'''^T'''f'''. As far as I am concerned, it is a matter of taste which you prefer, but the second is perhaps clearer. -- [[User:Jitse Niesen|Jitse Niesen]] ([[User talk:Jitse Niesen|talk]]) 20:46, 30 August 2005 (UTC)

All formulas have a lack of negative sign. For example:

:<math>\mathbf{(J^{T}J)\boldsymbol \delta = J^{T} [y - f(\boldsymbol \beta)]} \!</math>

should be:

:<math>\mathbf{(J^{T}J)\boldsymbol \delta = -J^{T} [y - f(\boldsymbol \beta)]} \!</math>

finding this bug took quite some time. And it should be pointed out, how to get to this formula. --vogt31337 9:00 26 January 2012 (UTC)
