Descrizione

extension

Which problem would you like to address? Please describe.
Currently, PEtab does not allow to express nonlinear mixed effects models (i.e containing fixed (population) and random (patient-specific) effects). These models are very common to represent inter-patient variability in pharmacological models. IIUC, such models are often represented in software like NONMEM, which was developed in the late 70s. I believe the field could benefit from a software independent model storage and exchange format.

Describe the solution you would like
In this spreadsheet, I have summarised a suggestion for a PEtab extension to introduce random effects in addition to the current format, which only allows to express fixed effects (happy to jump on a brief call to discuss in person).

Describe alternatives you have considered
There is a format called PharmML (Fig 2 here), which can express mixed effects, too. However, I don't think it is widely used yet, perhaps because the XML format is hard for humans to read and understand.

Additional context
I have no experience with NLME. While I have briefly discussed the suggestion linked in the spreadsheet with NLME experts, it would be good to get broader insight into a variety of use cases.
