    <h1>Function to calculate maximum time weighted average concentrations from kinetic models fitted with mkinfit</h1>

    <p>This function calculates maximum moving window time weighted average concentrations
(TWAs) for kinetic models fitted with <code><a href='mkinfit.html'>mkinfit</a></code>. 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.</p>
