Efficient Bayesian inference for multiple change-point and mixture innovation models

Giordani, Paolo; Kohn, Robert - 2006

Time series subject to parameter shifts of random magnitude and timing are commonly modeled with a change-point approach using Chib's (1998) algorithm to draw the break dates. We outline some advantages of an alternative approach in which breaks come through mixture distributions in state...

Formative measurement models in covariance structure analysis: Specification and identification

Hildebrandt, Lutz; Temme, Dirk - 2006

Many researchers seem to be unsure about how to specify formative measurement models in software programs like LISREL or AMOS and to establish identification of the corresponding structural equation model. In order to make identification easier, a new, mainly graphically-oriented approach is...

Improving MCMC Using Efficient Importance Sampling

Liesenfeld, Roman; Richard, Jean-François - 2006

This paper develops a systematic Markov Chain Monte Carlo (MCMC) framework based upon Efficient Importance Sampling (EIS) which can be used for the analysis of a wide range of econometric models involving integrals without an analytical solution. EIS is a simple, generic and yet accurate...

Defining and Characterizing Approaches to Farm Management

McBride, William D.; Johnson, James D. - In: Journal of Agricultural and Applied Economics 38 (2006) 01

Exploratory factor analysis was used to identify approaches to farm management based on a list of management questions posed to a sample of U.S. cash-grain farmers. Three approaches were identified by the factor analysis: price negotiation, long-term cost control, and input adjustment. Estimated...
