You'll need to convert something, but honestly I don't recall exactly what at this point.  You're treating it as a linear regression model, but that's not what this is.    You can see in the documentation how it's handled for a Tobit regression - they have the full code to score there and you'll need to do something similar for the lognormal.    I don't think you're using the right estimates to model your data either, as you've indicated. You need to use the parameter estimates. InEst exists before you model your data, you want OUTEST instead, which will hold your output estimates. https://documentation.sas.com/?docsetId=statug&docsetVersion=15.1&docsetTarget=statug_lifereg_syntax01.htm&locale=en   ...
