grofit (version 1.1.1-1)

The package was developed to fit fit many growth curves obtained under different conditions.

Description

The package was developed to fit fit many growth curves obtained under different conditions in order to derive a conclusive dose-response curve, for instance for a compound that potentially affects growth. grofit fits data to different parametric models (function gcFitModel) and in addition provides a model free spline fit (function gcFitSpline) to circumvent systematic errors that might occur within application of parametric methods.
