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 fit to the simultaneous broadband spectrum of Cygnus X-1 using the transition disk model [PDF]
, 1997 We have used the transition disk model to fit the simultaneous broad band ($2-500$ keV) spectrum of Cygnus X-1 from OSSE and Ginga observations. In this model, the spectrum is produced by saturated Comptonization within the inner region of the accretion ...

Simultaneous fitting of neutron star structure and cooling data
Physical Review C, 2019 Using a model for the equation of state and composition of dense matter and the magnitude of singlet proton superconductivity and triplet neutron superfluidity, we perform the first simultaneous fit of neutron star masses and radii determined from observations of quiescent low-mass x-ray binaries and luminosities and ages determined from observations ...

Likelihood-based inference for max-stable processes [PDF]
, 2009 The last decade has seen max-stable processes emerge as a common tool for the statistical modeling of spatial extremes. However, their application is complicated due to the unavailability of the multivariate density function, and so likelihood-based ...

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 ...

GAMLSS for high-dimensional data – a flexible approach based on boosting [PDF]
, 2010 Generalized additive models for location, scale and shape (GAMLSS) are a popular semi-parametric modelling approach that, in contrast to conventional GAMs, regress not only the expected mean but every distribution parameter (e.g.

Journal of Statistical Software, 2005 We describe an add-on package for the language and environment R which allows simultaneous fitting of several non-linear regression models. The focus is on analysis of dose response curves, but the functionality is applicable to arbitrary non-linear ...

Methods to derive the magnetopause from soft X-ray images by the SMILE mission
Geoscience Letters, 2022 Solar wind Magnetosphere Ionosphere Link Explorer (SMILE) is a novel self-standing mission dedicated to observing the solar wind–magnetosphere coupling via simultaneous in situ solar wind/magnetosheath plasma and magnetic field measurements, soft X-ray ...

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 ...
