The maximum time weighted average concentration for a moving window

+

If you generate your time series using sawtooth, +you need to make sure that the length of the time series allows +for finding the maximum. It is therefore recommended to check this using +plot.one_box using the window size for the argument +max_twa.

Details

+ +

The method working directly on fitted mkinfit objects uses the +equations given in the PEC soil section of the FOCUS guidance and is restricted +SFO, FOMC and DFOP models and to the parent compound
