training set with positive label only

mikymiky Member Posts: 1 Contributor I
Hello,

I need to use only positive labels in training set, how to do it? (like in SPSS)
I mean I can sign wich records are GOOD, but don't have opposites.
We are using Logistic Regression Model... (after Principal Component Analysis)

We have customers and finding new potencional customers (we don't have non-customers).

Example (fictional)
IDlabelpc_1pc_2pc_3
110.23-0.650.89this is my GOOD label
20-0.150.320.62I want to ommit this rows (we are faking them)
30-0.370.870.24I want to ommit this rows (we are faking them)
Thank you very much

    So you are creating fake data as negative examples? Do you want to use that data as training data? Then you can just learn the Logistic Regression as you would on any other dataset.
    Please let us know about any problems you have.

    Best regards,
