in mkin. If this argument is set to 'saemix', parameter transformations
are done in 'saemix' for the supported cases. Currently this is only
supported in cases where the initial concentration of the parent is not fixed,

<dt>degparms_start</dt>
<dd><p>Parameter values given as a named numeric vector will
be used to override the starting values obtained from the 'mmkin' object.</p></dd>
<dt>test_log_parms</dt>
<dd><p>If TRUE, an attempt is made to use more robust starting
values for population parameters fitted as log parameters in mkin (like
rate constants) by only considering rate constants that pass the t-test
when calculating mean degradation parameters using <a href="mean_degparms.html">mean_degparms</a>.</p></dd>
