Function to calculate maximum time weighted average concentrations from kinetic models fitted with mkinfit

- Source: R/max_twa_parent.R + Source: R/max_twa_parent.R

This function calculates maximum moving window time weighted average -concentrations (TWAs) for kinetic models fitted with mkinfit. +concentrations (TWAs) for kinetic models fitted with mkinfit. Currently, only calculations for the parent are implemented for the SFO, FOMC, DFOP and HS models, using the analytical formulas given in the PEC soil section of the FOCUS guidance.

Arguments

+
fit
+

An object of class mkinfit.

+
windows
+

The width of the time windows for which the TWAs should be +calculated.

+
M0
+

The initial concentration for which the maximum time weighted average over the decline curve should be calculated. The default is to use a value of 1, which means that a relative maximum time weighted average -factor (f_twa) is calculated.

k

The rate constant in the case of SFO kinetics.

t

The width of the time window.

alpha

Parameter of the FOMC model.

beta

Parameter of the FOMC model.

k1

The first rate constant of the DFOP or the HS kinetics.

k2

The second rate constant of the DFOP or the HS kinetics.

g

Parameter of the DFOP model.

tb

Parameter of the HS model.
