Bayesian Analysis of Boundary and Near-Boundary Evidence in Econometric Models with Reduced Rank
Basturk, Nalan; Hoogerheide, Lennart; van Dijk, Herman K. (Working Papers;11/2017, Working paper, 2017)Weak empirical evidence near and at the boundary of the parameter region is a predominant feature in econometric models. Examples are macroeconometric models with weak information on the number of stable relations, ... -
Forecast Density Combinations of Dynamic Models and Data Driven Portfolio Strategies
Basturk, Nalan; Borowska, Agnieszka; Grassi, Stefano; Hoogerheide, Lennart; van Dijk, Herman K. (Working Paper;10/2018, Working paper, 2018)A dynamic asset-allocation model is specified in probabilistic terms as a combination of return distributions resulting from multiple pairs of dynamic models and portfolio strategies based on momentum patterns in US industry ... -
The R Package Mitisem: Efficient and Robust Simulation Procedures for Bayesian Inference
Basturk, Nalan; Grassi, Stefano; Hoogerheide, Lennart; Opschoor, Anne; van Dijk, Herman K. (Working Papers;10/2017, Working paper, 2017)This paper presents the R package MitISEM (mixture of t by importance sampling weighted expectation maximization) which provides an automatic and flexible two-stage method to approximate a non-elliptical target density ...
