Results of fitting the DFOP model to Datasets A to B of FOCUS (2006)

FOCUS_2006_DFOP_ref_A_to_B.Rd

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.
