Multiple Regression

  1. Feb 3, 2012 #1
    It's been a long time since I've done (least squares?) multiple regression, is the calculation below correct?

    y data points
    6,054
    7,200
    6,243
    5,536
    4,879
    y hat = 5,984

    x data points
    414
    351
    425
    372
    328
    x hat = 378

    Sum of xy's residuals = 39,643
    Sum of (x-x hat) squared = 6,770
    slope = 5.86

    intercept = 5,984 - (5.86*378)
    intercept = 3,769

    y = 3,769 + (5.86*x)

    is that right?

    So for an x value of 400, it is

    y = 3,769 + (5.86*400)
    y = 3,769 + 2,344
    y = 6,113

    is that right?
