Goodness of Fit Tests for Simultaneous Autoregressive Series
Journal of the Royal Statistical Society Series B: Statistical Methodology, 1953 Summary The simplified method of derivation of Quenouille’s (1947) goodness of fit test for an autoregressive stationary series with discrete time, given by Bartlett and Diananda (1950), is extended in the present paper to the case of simultaneous autoregressive series, for which some interesting new features arise.

Noncrossing simultaneous Bayesian quantile curve fitting
, 2017 Bayesian simultaneous estimation of nonparametric quantile curves is a challenging problem, requiring a flexible and robust data model whilst satisfying the monotonicity or noncrossing constraints on the quantiles. This paper presents the use of the pyramid quantile regression method in the spline regression setting.

Simultaneous spectral and reverberation modelling of relativistic reflection in Mrk 335 [PDF]
, 2015 We present an X-ray spectral and timing model to investigate the broad and variable iron line seen in the high flux state of Mrk 335. The model consists of a variable X-ray source positioned along the rotation axis of the black hole that illuminates the ...

A Detection of the Baryon Acoustic Oscillation Features in the SDSS BOSS DR12 Galaxy Bispectrum [PDF]
, 2017 We present the first high significance detection ($4.1\sigma$) of the Baryon Acoustic Oscillations (BAO) feature in the galaxy bispectrum of the twelfth data release (DR12) of the Baryon Oscillation Spectroscopic Survey (BOSS) CMASS sample ($0.43 \leq z \

Most Likely Separation of Intensity and Warping Effects in Image Registration
, 2017 This paper introduces a class of mixed-effects models for joint modeling of spatially correlated intensity variation and warping variation in 2D images. Spatially correlated intensity variation and warp variation are modeled as random effects, resulting ...

Observational asteroseismology of hot subdwarf stars [PDF]
, 2010 Hot subdwarf stars are particularly challenging for asteroseismology due to their rapid pulsation periods, intrinsic faintness and relative rarity both in the field and in clusters.

International Journal of Mathematics and Mathematical Sciences, 1988 Efficient and unbiased estimates of the parameters of the differential system, as well as simultaneous fiducial limits, are obtained through an (eventually weighted) least-squares fitting to a Taylor expansion of the concentration of the products of the ...

, 2010 Using data from the Heliospheric Imagers (HIs) onboard STEREO, it is possible to derive the direction of propagation of coronal mass ejections (CMEs) in addition to their speed with a variety of methods. For CMEs observed by both STEREO spacecraft, it is

Active galactic nuclei at z ~ 1.5: III. Accretion discs and black hole spin [PDF]
, 2016 This is the third paper in a series describing the spectroscopic properties of a sample of 39 AGN at $z \sim 1.5$, selected to cover a large range in black hole mass ($M_{BH}$) and Eddington ratio ($L/L_{Edd}$). In this paper, we continue the analysis of
