    So, I am working on a project for my business stats class. I have to use minitab for the project. My project is based around basic regressions. I have found an acceptable regression equation:

    regress c1 5 c3-c5 c19 c61.

    For the next part of the project, I need to find the value for c1. I have all other data, and do not know how to use what I found before to get c1. Here is the report I got for the equation above. If anyone can help, please do! I am a loss.

    Regression Analysis: CHEMP versus TAX, UNEMP, POP05, COLL, DEPLIB

    The regression equation is
    CHEMP = 3.28 - 0.000606 TAX - 0.775 UNEMP + 0.000004 POP05 + 0.279 COLL
    + 0.000030 DEPLIB


    Predictor Coef SE Coef T P
    Constant 3.282 1.641 2.00 0.051
    TAX -0.0006064 0.0001199 -5.06 0.000
    UNEMP -0.7754 0.1108 -7.00 0.000
    POP05 0.00000364 0.00000074 4.90 0.000
    COLL 0.27944 0.05347 5.23 0.000
    DEPLIB 0.00003022 0.00002659 1.14 0.261


    S = 1.20634 R-Sq = 90.5% R-Sq(adj) = 89.6%

    R denotes an observation with a large standardized residual.
    X denotes an observation whose X value gives it large leverage.

    Good lord how can that ever be used in business? I thought the general rule of business was lie, cheat, steal, and repeat. :D

    glad you could because i don't think i'd be way out of line in saying that there probably aren't that many active posters here who could.

    so do i but not too many responded so that lead me to think that we don't know.

    i could be wrong obviously.

    Haha I was kidding (somewhat). I knew the chances of someone knowing how to use that program was extremely low but I figured I'd post it anyways. In short, I agree with you. :up:
