This paper extends the conventional Bayesian mixture of normals model by permitting state probabilities to depend on observed covariates. The dependence is captured by a simple multinomial probit model. A conventional and rapidly mixing MCMC algorithm provides access to the posterior distribution at modest computational cost. This model is competitive with existing econometric models, as docume...

We study the problem of identi cation of the long regression E(y jx; z) when the short conditional distributions P (y jx) and P (z jx) are known but the long conditional distribution P (y jx; z) is not known. This problem often arises when a researcher utilizes data from two separate data sets. (A leading example is the ecological inference problem of political science, where voting behavior ac...

this study was conducted in split plot design based on a randomized complete block design in naghadeh region, urmia, iran in 2009-10. two sowing patterns including a1) single row planting with 50 cm between-row spacing, and a2) two rows planting on the hill with 40 cm distance and 50 cm between-row spacing (40×50) were allocated to main plots and four furrow compactions including b1) control, b...

We analyze herding behavior in the Chinese stock markets context of COVID-19 pandemic using cross-sectional absolute deviation (CSAD) model proposed by Chang et al. (2000) to detect time period between January 30, 2001, and June 12, 2020. consider prices for all firms listed (A-shares) on Shanghai Stock Exchange (SHSE) Shenzhen (SZSE) China. report presence during under study that becomes stron...

Twin-roll casting AZ31 Mg alloy sheets have been fabricated by normal unidirectional-rolling, head-to-tail rolling, and clock-rolling, respectively. It has been demonstrated that head-to-tail rolling is the most effective to refine the microstructure and weaken the basal texture among the three rolling routes. Excellent integrated tensile properties can be obtained by the head-to-tail rolling. ...

This article considers the seemingly unrelated regression (SUR) model first analyzed by Zellner (1962). We describe estimators used in the basic model as well as recent extensions.
