Grid-based simulation and the method of conditional least squares [PDF]

open access: yesProceedings of the 28th conference on Winter simulation - WSC '96, 1996
This paper is concerned with the use of simulation to compute the conditional expectations that arise in the method of conditional least squares. Our approach involves performing simulations at each point on a discrete grid imbedded within a statistical parameter space.

A Contribution to the Conditioning of the Total Least-Squares Problem [PDF]

open access: yesSIAM Journal on Matrix Analysis and Applications, 2011
We derive closed formulas for the condition number of a linear function of the total least squares solution. Given an over determined linear system Ax=b, we show that this condition number can be computed using the singular values and the right singular vectors of [A,b] and A.

Computing the conditioning of the components of a linear least‐squares solution [PDF]

open access: yesNumerical Linear Algebra with Applications, 2008
AbstractIn this paper, we address the accuracy of the results for the overdetermined full rank linear least‐squares problem. We recall theoretical results obtained in (SIAM J. Matrix Anal. Appl. 2007; 29(2):413–433) on conditioning of the least‐squares solution and the components of the solution when the matrix perturbations are measured in Frobenius ...

The conditioning of least‐squares problems in variational data assimilation [PDF]

open access: yesNumerical Linear Algebra with Applications, 2018
SummaryIn variational data assimilation a least‐squares objective function is minimised to obtain the most likely state of a dynamical system. This objective function combines observation and prior (or background) data weighted by their respective error statistics.

Least-Squares Conditional Density Estimation

open access: yesIEICE Transactions on Information and Systems, 2010
Estimating the conditional mean of an input-output relation is the goal of regression. However, regression analysis is not sufficiently informative if the conditional distribution has multi-modality, is highly asymmetric, or contains heteroscedastic noise. In such scenarios, estimating the conditional distribution itself would be more useful.

First-Order Integer-Valued Moving Average Process with Power Series Innovations

open access: yesJournal of Statistical Theory and Applications (JSTA), 2020
In this paper, we introduce a first-order nonnegative integer-valued moving average process with power series innovations based on a Poisson thinning operator (PINMAPS(1)) for modeling overdispersed, equidispersed and underdispersed count time series ...

Asymptotic behaviour of estimators of the parameters of nearly unstable INAR(1) models [PDF]

open access: yes, 2003
A sequence of first-order integer-valued autoregressive type (INAR(1)) processes is investigated, where the autoregressive type coefficients converge to 1.

Maximum-Likelihood Estimation in a Special Integer Autoregressive Model

open access: yesEconometrics, 2020
The paper is concerned with estimation and application of a special stationary integer autoregressive model where multiple binomial thinnings are not independent of one another.
