A Simple Robust Procedure in Instrumental Variables Regression
Xiyu Jiao
A common concern in empirical modelling centres around whether estimated regression coefficients are affected by a small set of outlying observations. To conduct outlier robustness…
Causal State-Dependent Local Projections
Joel M. David, Raffaella Giacomini, Xiyu Jiao +1
State-dependent local projections (LPs) are widely used to study how causal effects vary as a function of economic states, but shock exogeneity alone does not identify this respons…
Projected distances to host galaxy reduce SNIa dispersion
R. Hill, H. Shariff, R. Trotta +8
We use multi-band imagery data from the Sloan Digital Sky Survey (SDSS) to measure projected distances of 302 supernova type Ia (SNIa) from the centre of their host galaxies, norma…
Standardizing Type Ia supernovae using Near Infrared rebrightening time
Hikmatali Shariff, Suhail Dhawan, Xiyun Jiao +3
Accurate standardisation of Type Ia supernovae (SNIa) is instrumental to the usage of SNIa as distance indicators. We analyse a homogeneous sample of 22 low-z SNIa, observed by the…
BAHAMAS: new SNIa analysis reveals inconsistencies with standard cosmology
H. Shariff, X. Jiao, R. Trotta +1
We present results obtained by applying our BAyesian HierArchical Modeling for the Analysis of Supernova cosmology (BAHAMAS) software package to the 740 spectroscopically confirmed…
A Corrected and More Efficient Suite of MCMC Samplers for the Multinomal Probit Model
Xiyun Jiao, David A. van Dyk
The multinomial probit (MNP) model is a useful tool for describing discrete-choice data and there are a variety of methods for fitting the model. Among them, the algorithms provide…
Metropolis-Hastings within Partially Collapsed Gibbs Samplers
David A. van Dyk, Xiyun Jiao
The Partially Collapsed Gibbs (PCG) sampler offers a new strategy for improving the convergence of a Gibbs sampler. PCG achieves faster convergence by reducing the conditioning in…
