Approximating conditional distributions by the mixed Edgeworth-saddlepoint expansion
Department of Theoretical Statistics, University of Aarhus Denmark
Conditional density and distribution functions can be approximated by the mixed Edgeworth-saddlepoint expansion. This technique is briefly described, and its use and character are illustrated by three examples concerning miscellaneous exponential families of order two.
