FitIsoGrowth {biogrowth}  R Documentation 
FitIsoGrowth class
Description
The class FitIsoGrowth has been superseded by the toplevel class GrowthFit, which provides a unified approach for growth modelling.
Still, it is still returned if the superseded fit_isothermal_growth()
is called.
It is a subclass of list with the items:
data: data used for model fitting
model: name of the primary inactivation model
starting_point: initial value of the model parameters
known: fixed model parameters
fit: object returned by
modFit()
best_prediction: model prediction for the model fitted.
