You must first specify some structural equation for the relationship between
TC and LC, (and other relevant variables). Estimate this relationship using
gretl. (How you do this depends on your model and the possible presence of
other endogenous models.) You can then easily estimate the required
marginal effect.

Hi all,
Say I have a two series: Total Cost(TC) and Labour Cost(LC). I wish
to obtain another series for the partial derivative of TC with respect to LC
(dTC/dLC). Any hint on how this could be done via Grelt.
Thanks
