Abstract: In this short paper, we investigate sensitivity and robustness of neutral delay
differential models to small perturbations in the parameters that occur in the models, using
variational approach. The technique provides a guidance for the modelers to determine
the most informative data for a specific parameter. It may also help modelers to select the
best fit model to the observations.
