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 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

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...

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...

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...
