    Default Data fitting to Linear result

    Hello,

    Complete newbie to Data Mining and not very good at maths I was wondering if WEKA can do something like this.
    ID4 gain ID10 ID1 ID3_75C
    2665 1.482 105 7040 8005
    Above is a sample of data I get from a thermal device calibration. The ID_75C in an ideal scenario need to equal 9500, but due to poor calibration does not. I need WEKA to give me an equation that most fits the linear results (9500) by using the other data available.

    If I am running WEKA using the available data, including the ID3_75C from the device I can get a solution to fit the "wrong data" but if I enter a column manually and populate it with the 9500 result and then try to solve for it I always get ID3_75C = + 9500, it ignore all the other variables and I need it to do the opposite, ignore ID3_75C and solve for it using everything else available.

    Any help would be greatly appreciated

    Thank You and Kind Regards,

    DrD

    Do you have more than one row of data? And is your ideal target value ever different from 9500? If not, then ID3_75C = 9500 is the optimal solution :-)

    Cheers,
    Mark.
