FOCUS_2006_HS_ref_A_to_F


A table with the fitted parameters and the resulting DT50 and DT90 values
generated with different software packages. Taken directly from FOCUS (2006).
The results from fitting the data with the Topfit software was removed, as
the initial concentration of the parent compound was fixed to a value of 100
in this fit.


datasets


The FOCUS Kinetics Report first published in 2006 describes mathematical
models and recommends statistical methods for the evaluation of
chemical degradation data. This package implements fitting the kinetic
models suitable for observations of the decline of a single chemical
compound (no metabolite formation/decline or multi-compartment kinetics).
Please note that no warranty is implied for correctness of results or
fitness for a particular purpose.  'kinfit' is maintained, but not
actively developed at the moment. Please check the 'mkin' package for an
actively developed package for kinetic evaluations of degradation data.
