Regularization methods for high-dimensional instrumental variables regression with an application to genetical genomics
Causal inference Confounding Endogeneity Sparse regression
2016/1/25
In genetical genomics studies, it is important to jointly analyze gene expression data and genetic variants in exploring their associations with complex traits, where the dimensionality of gene expres...

Space-time variations of the Umbria-Marche region instrumental seismicity
b value seismicity Apennines
2015/9/29
In the Umbria-Marche region, space and time variations concerning the b value were studied by instrumental seismicity from January 1987 to May 1999, according to the Bender method. Data were divided i...
The chapter discusses generalized method of moments (GMM) estimation
methods for spatial models. Much of the discussion is on GMM estimation of
Cliff-Ord-type models where spatial interactions are m...
Re-evaluation of early instrumental earthquake locations: methodology and examples
earthquake location macroseismic locations
2015/9/14
The difficulties of locating earthquakes in the early instrumental period are not always fully appreciated. The networks were sparse, and the instruments themselves were of low gain, often had inappro...
The role of instrumental versus macroseismic locations for earthquakes of the last century: a discussion based on the seismicity of the North-Western Apennines (Italy)
historical seismicity velocity propagation model Joint Hypocentral Determination
2015/9/10
Many seismological observatories began to record and store seismic events in the early years of the twentieth century,
contributing to the compilation of very valued databases of both phase pickings ...
Instrumental and Chemometric Analysis of Automotive Clear Coat Paints by Micro Laser Raman and UV Microspectrophotometry
Raman microspectrophotometry clear coat automotive paint chemometrics forensic
2015/5/21
Automotive paints have used an ultraviolet (UV) absorbing clear coat system for nearly thirty years. These clear coats have become of forensic interest when comparing paint transfers and paint samples...
Reconstructing the East Asian monsoon response to major volcanic eruptions: A test of model skill with instrumental and paleoclimate data
Volcanic eruption climate change ancient climate records volcanoes the tropics precipitation
2014/10/22
Global and regional-scale climatic changes caused by volcanic eruptions are difficult to discern conclusively based on limited 20th century climate records. Analyses of paleoclimate records and global...
LASSO Methods for Gaussian Instrumental Variables Models
LASSO Methods Gaussian Instrumental Variables Models
2011/3/2
In this note, we propose the use of sparse methods (e.g. LASSO, Post-LASSO,p LASSO, and Post-
p LASSO) to form rst-stage predictions and estimate optimal instru-ments in linear instrumental variable...
The instrumental polarization of the Nasmyth focus polarimetric differential imager NAOS/CONICA (NACO) at the VLT - Implications for time-resolved polarimetric measurements of Sgr A*
the Nasmyth focus polarimetric differential imager NAOS/CONICA (NACO)
2011/1/10
We report on the results of calibrating and simulating the instrumental polarization properties of the ESO VLT adaptive optics camera system NAOS/CONICA (NACO) in the Ks-band. We use the Stokes/Muelle...
Venus wind map at cloud top level with the MTR/THEMIS visible spectrometer. I. Instrumental performance and first results
Venus Wind Clouds Visible Spectrometry
2010/11/15
Solar light gets scattered at cloud top level in Venus’ atmosphere, in the visible range, which corresponds to the altitude of 67 km. We present Doppler velocity measurements performed with the high r...
Impact of Instrumental Systematics on the CMB Bispectrum
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/28
We study the effects of instrumental systematics on the estimation of primordial non-Gaussianity using the cosmic microwave background (CMB) bispectrum from both the temperature and the polarization a...
