Dear all,

I am a PhD student working on NONMEM as a new user. I am working on external 
evaluation of some of the selected published population PK models. While trying 
to implement one of the models in NONMEM, I realised that if I code 
log-transformed aspartate aminotransferase (LAST) as LAST = LOG(AST), the sdtab 
 output is giving me the In(AST) value instead of a LOG(AST) value. Was 
wondering if NONMEM interprets all Log (x) as Log e (x) instead of Log 10 (x)?

Thank you.

Best Regards,

Ranita Kirubakaran
