I have a oversampled data set. I know that the proportion of the target event in the population was 2%. How do I correct for this?<BR />To my understanding, the event-based option is used when you want to oversample a data set that is not yet oversampled so I cannot use that. I do not have the un-oversampled data set and do not know how it was oversampled, only the information mentioned above.</P> Thu, 29 Aug 2024 09:37:18 GMT https://communities.sas.com/t5/SAS-Software-for-Learning/Correcting-for-over-sampling-in-SAS-Viya/m-p/941670#M2231 JakoBriel 2024-08-29T09:37:18Z Re: Correcting for over-sampling in SAS Viya https://communities.sas.com/t5/SAS-Software-for-Learning/Correcting-for-over-sampling-in-SAS-Viya/m-p/941713#M2232 <P>Which version of SAS Visual Analytics are you using?

Here is a post that will explain the adjustments needed:<BR /><A href="https://support.sas.com/kb/22/601.html" target="_blank">https://support.sas.com/kb/22/601.html</A> Fri, 30 Aug 2024 12:24:14 GMT https://communities.sas.com/t5/SAS-Software-for-Learning/Correcting-for-over-sampling-in-SAS-Viya/m-p/941937#M2261 tom_grant 2024-08-30T12:24:14Z
