No full textIn this paper some new properties and computational
tools for finding KL-optimum designs are provided.
KL-optimality is a general criterion useful to select
the best experimental conditions to discriminate between
statistical models. A KL-optimum design is obtained from
a minimax optimization problem, which is defined on a
infinite-dimensional space. In particular, continuity of the
KL-optimality criterion is proved under mild conditions; as
a consequence, the first-order algorithm converges to the set
of KL-optimum designs for a large class of models. It is also
shown that KL-optimum designs are invariant to any scaleposition
transformation. Some examples are given and discussed,
together with some practical implications for numerical
computation purposes.
