Calibration diagnostics for point process models via the probability integral transform
Calibration diagnostics point process models probability integral transform
2013/6/14
We propose the use of the probability integral transform (PIT) for model validation in point process models. The simple PIT diagnostics assess the calibration of the model and can detect inconsistenci...
We propose a new method named calibrated multivariate regression (CMR) for fitting high dimensional multivariate regression models. Compared to existing methods, CMR calibrates the regularization for ...

Probabilistic temperature forecasting with statistical calibration in Hungary
2013/4/27
Weather forecasting is mostly based on the outputs of deterministic numerical weather forecasting models. Multiple runs of these models with different initial conditions result in forecast ensembles w...

What is the response of the climate system to anthropogenic forcings? This question is addressed typically using projections from climate models. The uncertainty surrounding current climate projection...
Prediction and Computer Model Calibration Using Outputs From Multi-fidelity Simulators
Computer Experiment Gaussian process Markov Chain Monte Carlo.
2012/9/17
Computer codes are widely used to describe physical processes in lieu of physical observations.In some cases, more than one computer simulator, each with di erent degrees of delity, can be used to ex...
We consider the problem of calibration and the GREG method as suggested and studied in Deville and Sarndal (1992). We show that a GREG type estimator is typically not minimal variance unbiased estimat...
Calibration and filtering for multi factor commodity models with seasonality: incorporating panel data from futures contracts
Multi-Factor Commodity Spot Price Stochastic Volatility Milstein Adaptive Markov chain Monte Carlo Particle filter Rao-Blackwellization
2011/6/21
We examine a general multi-factor model for commodity spot prices and futures valuation. We extend
the multi-factor long-short model in [1] and [2] in two important aspects: firstly we allow for both...
Accounting for Calibration Uncertainties in X-ray Analysis: Effective Areas in Spectral Fitting
Accounting for Calibration Uncertainties Effective Areas in Spectral Fitting X-ray Analysis
2011/3/25
While considerable advance has been made to account for statistical uncertainties in astronomical analyses, systematic instrumental uncertainties have been generally ignored. This can be crucial to a ...
Improving PSF calibration in confocal microscopic imaging---estimating and exploiting bilateral symmetry
confocal microscopic imaging PSF calibration estimating exploiting bilateral symmetry
2011/3/18
A method for estimating the axis of reflectional symmetry of an image $f(x,y)$ on the unit disc $D=\{(x,y):x^2+y^2\leq1\}$ is proposed, given that noisy data of $f(x,y)$ are observed on a discrete gri...

Calibration Linear regression estimator GREG Estimation of total andvariance
2010/3/18
In the present investigation, we build a bridge between the generalized regression
(GREG) estimator due to Deville and Sarndal (1992) and the linear regression estimator
due to Hansen, Hurwitz and M...
