Note that a method for calculating maximum moving window time weighted average concentrations for a model fitted by ‘mkinfit’ or from parent decline model parameters is included in the max_twa_parent()
function. If the same is needed for metabolites, the function pfm::max_twa()
from the ‘pfm’ package can be used.
