Analysis and Estimation of Geographical and Topographic Influencing Factors for Precipitation Distribution over Complex Terrains: A Case of the Northeast Slope of the Qinghai–Tibet Plateau

Atmosphere, 2018
Due to the complex terrain, sparse precipitation observation sites, and uneven distribution of precipitation in the northeastern slope of the Qinghai–Tibet Plateau, it is necessary to establish a precipitation estimation method with strong ...

Conditional and marginal relative risk parameters for a class of recursive regression graph models

, 2018
In linear regression modelling the distortion of effects after marginalizing over variables of the conditioning set has been widely studied in several contexts. For Gaussian variables, the relationship between marginal and partial regression coefficients

Molecular regulatory mechanisms of depression-related thrombosis risk [PDF]

Journal of Medical Biochemistry
Background: This is mainly because depression is a COM-mon psychiatric condition affecting more than 280 million people worldwide and is increasingly linked to an increased risk of thrombotic events, including deep vein thrombosis (DVT) and pulmonary ...

Automatic Fine Co-Registration of Datasets from Extremely High Resolution Satellite Multispectral Scanners by Means of Injection of Residues of Multivariate Regression

Remote Sensing
This work presents two pre-processing patches to automatically correct the residual local misalignment of datasets acquired by very/extremely high resolution (VHR/EHR) satellite multispectral (MS) scanners, one for, e.g., GeoEye-1 and Pléiades, featuring

Multivariate Student -t Regression Models: Pitfalls and Inference [PDF]

We consider likelihood-based inference from multivariate regression models with independent Student-t errors. Some very intruiging pitfalls of both Bayesian and classical methods on the basis of point observations are uncovered. Bayesian inference may be

From Scratch: A Didactic Example of Multivariate Regression in Python [PDF]

Tutorials in Quantitative Methods for Psychology
Although Python has the statsmodels library that can be used to perform different statistical analyses, including multiple regression, it has not yet implemented multivariate regression as one of its methods.

A nonparametric regression cross spectrum for multivariate time series [PDF]

We consider dependence structures in multivariate time series that are characterized by deterministic trends. Results from spectral analysis for stationary processes are extended to deterministic trend functions.

Simulation of arthropod abundance from plant composition [PDF]

Computational Ecology and Software, 2011
The relationship between arthropod abundance and plant composition is extremely complex. It is very hard to develop a mechanistic model to describe the relationship.

A local dynamic conditional correlation model [PDF]

This paper introduces the idea that the variances or correlations in financial returns may all change conditionally and slowly over time. A multi-step local dynamic conditional correlation model is proposed for simultaneously modelling these components ...

Multivariate probit regression using simulated maximum likelihood [PDF]

We discuss the application of the GHK simulation method to maximum likelihood estimation of the multivariate probit regression model, and describe and illustrate a Stata program mvprobit for this purpose.
