Talk:Polynomial regression
In which norm the approximation has to be done? Euclidean? C-norm? The basis seem to be xn? --Dmitry-kazakov 14:10, 4 June 2008 (MDT)
Any norm could be used. The task is not about mathematics. This task is intended as a subtask. The produced polynoms are used as labels for simple charts, therefore any norm will suffice. You may create a new task if a more formal task statement is desirable. The basis is 1, x, x2, x3, ..., xn. `n' is supposed to be known. -- Geka Sua 08:04, 7 June 2008 (MDT)
About fortran
It is quickly coded, and while trying to remember things. It works anyway, but I suppose there's a better way. the method I've followed is straightforwardly from Wolfram.com --ShinTakezou 23:58, 18 December 2008 (UTC)
