SPECIFICATION OF HYPER-PARAMETERS FOR NORMAL PRIOR DISTRIBUTIONS INDUCED ON LOG-LINEAR PARAMETERS
Haydar Demirhan, Canan Hamurkaroğlu · 2006
In this paper, the specification of hyper-parameters of the prior distribution of log-linear parameters is taken into account. Determination of a prior for the log-linear parameters is considered. Some approaches are given to specify the covariance matrix of the prior distribution, which reflects our degree of belief in the prior information. A new approach is proposed to specify the dispersion parameter of the prior distribution. An example is given to clarify the argued matters and a sensitivity analysis is also conducted.
