    Smile Understanding Prediction Limits

    Hi guys!
    I'm also starting with predictive analysis and regression models.
    I've managed to get a nice looking prediction formula with 86.8% of R2. Then I re-run the regression (I'm using MiniTab 13) and selected the options to get Confidence Limits and Prediction Limits...

    My question is... how do I interpret these??

    For example, I'm testing the likelihood of payment (Paid = 1, Not paid = 0) and I got this Limits from MiniTab:

    CLIM3 CLIM4 PLIM3 PLIM4
    0.85443 0.87967 0.51282 1.22128
    1.32188 1.34515 0.97932 1.68771

    My first question is, how can I interpret these numbers?

    I thought I had to take the Prediction Limits to see the range of probability they had to pay... but I can't have 51% to 122%, can I?

    Please???

    Re: Understanding Prediction Limits

    Did you do a logistic regression, or a linear regression? I'm guessing linear, since your estimates for payment are not staying between 0 and 1.
