For many longitudinal studies involving a discrete (count or categorical) response variable, and for some studies involving a continuous response variable, it is difficult to justify a fully parametric model for the data. In these circumstances, the method of GEE provides consistent...

A series expansion for Heckman-Opdam hypergeometric functions φλ is obtained for all λ ∈ a∗ C . As a consequence, estimates for φλ away from the walls of a Weyl chamber are established. We also characterize the bounded hypergeometric functions and thus prove an analogue of the celebrated theorem of Helgason and Johnson on the bounded spherical functions on a Riemannian symmetric space of the no...
