Results of fitting the HS model to Datasets A to F of FOCUS (2006)

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.

Usage

FOCUS_2006_HS_ref_A_to_F

Format

A data frame containing the following variables.

package: a factor giving the name of the software package
M0: The fitted initial concentration of the parent compound
tb: The fitted tb parameter
k1: The fitted k1 parameter
k2: The fitted k2 parameter
DT50: The resulting half-life of the parent compound
DT90: The resulting DT90 of the parent compound
dataset: The FOCUS dataset that was used
