Fitting Gastric Emptying Curves with R

What we present

LinExp modelOn this page we present technical details and cookbook examples how to use the open source statistical framework R to estimate parameters of gastric emptying with the standard power exponential function (Elashoff et al, 1982) and our LinExp model.

This page complements three papers on the LinExp model by the Gastric Motility Workgroup at the ETH and the University Hospital of Zürich. The first paper is more technical, the other two present study results analyzed with LinExp.. Pharmacodynami modelling of gastric Empyting under pentagastrin
