which allows for skewness in the form of contraction/dilation along a subset of the prinicpal axis. The paper derives some … properties for this distribution, including its moment generating function, multivariate skewness and kurtosis. Maximum … likelihood estimation is discussed and a complete Bayesian analysis of the multivariate split normal distribution is developed. …

This note presents a nonparametric Bayesian approach to fitting a distribution to the survey data provided in Kilian and Zha (2002) regarding the prior for the half-life of deviations from purchasing power parity (PPP). A point mass at infinity is included. The unknown density is represented as...

DSGE models are typically estimated using Bayesian methods, but a researcher may want to estimate a DSGE model with full information maximum likelihood (FIML) so as to avoid the use of prior distributions. A very robust algorithm is needed to find the global maximum within the relevant parameter...

We ask whether Bayesian estimation creates a potential estimation bias as compared with standard estimation techniques … based on the data, such as maximum likelihood or indirect estimation. We investigate this with a Monte Carlo experiment in … alternative. The Bayesian estimation of macro models may thus give very misleading results by placing too much weight on prior …

We construct a copula from the skew t distribution of Sahu, Dey & Branco (2003). This copula can capture asymmetric and extreme dependence between variables, and is one of the few copulas that can do so and still be used in high dimensions effectively. However, it is difficult to estimate the...

This paper deals with estimating peaked densities over the interval [0,1] using the Uneven Two-Sided Power Distribution (UTP). This distribution is the most complex of all the bounded power distributions introduced by Kotz and van Dorp (2004). The UTP maximum likelihood estimator, a result not...

We introduce two new methods for estimating the Marginal Data Density (MDD) from the Gibbs output, which are based on exploiting the analytical tractability condition. Such a condition requires that some parameter blocks can be analytically integrated out from the conditional posterior...
