A significant limitation in current determinations of Parton Distribution Functions (PDFs), which describe the structure of protons, is that the impact of theoretical uncertainties is not systematically accounted for. I will present two frameworks for the inclusion of additional sources of theoretical uncertainty in PDF fits, and present the first studies of the effects of missing higher-order uncertainties, which are estimated using scale variations, on PDFs in the context of the NNPDF approach.
