Unimodal regression in the two-parameter exponential family with constant or known dispersion parameter
Abstract: In this paper we discuss statistical methods for
curve-estimation under the assumption of unimodality for variables with
distributions belonging to the two-parameter exponential family with known
or constant dispersion parameter. We suggest a non-parametric method based
on monotonicity properties. The method is applied to Swedish data on
laboratory verified diagnoses of influenza and data on inflation from an
episode of hyperinflation in Bulgaria.
