Statistical analysis of error for fourth-order ordinary differential equation solvers

He, Bo; Martin, Clyde - In: Journal of Applied Statistics 36 (2009) 8, pp. 835-852

We develop an autoregressive integrated moving average (ARIMA) model to study the statistical behavior of the numerical error generated from three fourth-order ordinary differential equation solvers: Milne's method, Adams-Bashforth method and a new method that randomly switches between the Milne...

Evaluation of confidence intervals for the kappa statistic when the assumption of marginal homogeneity is violated

Parpia, Sameer; Koval, John; Donner, Allan - In: Computational Statistics 28 (2013) 6, pp. 2709-2718

This article studies the robustness of confidence interval construction for the intraclass kappa statistic based on a dichotomous response when the assumption of marginal homogeneity across two raters is violated. Two methods of construction are considered: the goodness-of-fit approach and the...

Bayesian Model Averaging and Weighted Average Least Squares : Equivariance, Stability, and Numerical Issues

Magnus, Jan R.; De Luca, G. - Tilburg University, Center for Economic Research - 2011

This article is concerned with the estimation of linear regression models with uncertainty about the choice of the explanatory variables. We introduce the Stata commands bma and wals which implement, respectively, the exact Bayesian Model Averaging (BMA) estimator and the Weighted Average Least...

Levy Subordinator Model: A Two Parameter Model of Default Dependency

Balakrishna, B S - Volkswirtschaftliche Fakultät, … - 2010

Subordinators are Levy processes with non-decreasing sample paths. They are natural processes to model default dependency. They help ensure that the loss process is non-decreasing leading to a promising class of dynamic models. The simplest subordinator is the Levy subordinator, a maximally...

Wind energy assessment: Masdar City case study

Janajreh, Isam; Su, Liu; Alan, Fathi - In: Renewable Energy 52 (2013) C, pp. 8-15

Annual wind data at Masdar City (24.4202° N, 54.6132° E) has been recorded in attempt to assess wind energy potential. Thereby, accurate wind energy production can be assessed for a given region. The vertical wind profile is inferred and was appropriately fitted with power law profile. The...
