| Abstract: | Liang & Zeger's generalized estimating equation approach for analysis of longitudinal data is extended to marginal distributions of dispersion model type. This includes for example the von Mises and simplex distributions, suitable for angles and proportions, respectively. Both modelling of position and joint modelling of position and dispersion is considered, and the method is applied to a set of bird orientation data. |
