Abstract
We consider the issue of parameter sensitivity in models based on alternative discrete-time operators (ADTOs). A generic first-order ADTO is proposed that encompasses all the known first-order ADTOs introduced so far in the literature. New bounds on the operator parameters are derived, and a new algorithm is given for optimally selecting the parameters to give minimum parameter sensitivity
