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

+
+ + +

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

+ + + 
max_twa_parent(fit, windows)
+ +

Arguments

+ + + + + + + + + + +
fit

An object of class mkinfit.

windows

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

+ +

Value

+ +

A numeric vector, named using the windows argument.
