    Least Squared Error Function

    Hello,
    Any one know how to code up a simple function to find the Least Squared Error for an array if values. Have looked at math and seems really complex.
    Say:

    Code:
    double ReturnLeastSquaredError( int Items, double Data[] )
{
??????????????
}
    Many thanks

    You have to give an attempt first and ask specific questions.

    No, seriously, it's part of the homework policy. And we cannot even begin to imagine what problem you're having if you aren't specific. Plus we don't want to write everything for you.

    What if you just asked a specific question: what are you confused about?

    Try looking up "least squares error" on google, and do some basic research yourself.

    Sure we could do that for you, but you won't learn anything at all. Further, you won't understand what we give you and that will just beg more questions from you.

    If you can't even demonstrate that you've even done the most basic of research, then just give up as a programmer.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    I guess the big issue is here that most of these web forum are over run with the unemployable that have nothing better to do or children that just like to post.
    I am neither.. Up to my eyes in work and needed little simple help.

    I post when I can make a contribution, other wish I stay of the tread.

    I ask for the second time… How do I get my user id removed please?

    Another pointless forum

    someone who's just not grateful for the help he gets, even in a little forum like this. How do we avoid people like this?

    Well, I have decided to satisfy PartOfTheSoluti's deepest and darkest desires.

"Finding the smallest program that demonstrates the error" is a powerful debugging tool.
