This study reports the results of a Monte Carlo evaluation of the small sample performance of ordinary least sqares (OLS), ridge and jackknife estimators of regression coefficients. The primary criteria of evaluation are the mean square error (MSE) of the regression coefficients and the size of the t-statistics associated with these coefficients. The conditions studied are derived from a design in which two factors are varied: the sample size to number of predictors (N/p) ratio and the metric...

Sensitivity of designed plans and computed risks to changes in the prior parameters has been studied in this report. In the first part, the study is pursued for specified changes in the prior mean and the shape parameter. The second part involves an empirical quantification of the uncertainty in parameter estimates by using Monte Carlo simulation, likelihood contours and the asymptotic distribution of the parametric estimators.

In estimating the coefficient of an endogenous variable in a single equation of a system of linear equations, Anderson and Sawa (1973) expressed the distribution of the two-stage least-squares (TSLS) estimator as a doubly noncentral F distribution. We relax their assumption of independent Gaussian errors, taking instead a scale mixture of spherical Gaussian laws in a class containing the spherical stable distributions. The resulting distribution of the TSLS estimator is a mixture of doubly...

A new approach for comparison and modification of M-estimators is introduced and implemented. The problem considered is that of robust estimation of a location parameter. Specific attention is given to the epsilon-contaminated normal model. The analytical method introduced is based upon the asymptotic variance of the estimator, the asymptotic variance being considered as a functional over the space of distribution functions. The behavior of this functional is investigated with respect to...

The state estimation problem for bilinear stochastic systems evolving on compact Lie groups and homogeneous spaces is considered. The problem is motivated by some applications involving rotational processes in three dimensions. The theory of harmonic analysis on compact Lie groups is used to define assumed density approximations which result in implementable suboptimal estimators for the state of the bilinear system. The results of Monte Carlo simulations are reported; these indicate that...

It is now generally recognized that the next frontier in the commercial air travel will be achieved by an optimum combination of the concepts being used for the air and space transports. It will depend upon the new engines specifically designed to meet the demanding strength, temperature, environment and economy requirements. The successful development of an advanced propulsion system for a 21st Century High Speed Civil Transport will require key advances in the combustor system. Minimizing...

The number of test samples used to characterize the fatigue constants needed for failure predictions for ceramic materials determines the confidence in these predictions. The statistical reproducibility of the dynamic and static fatigue experiments used to measure the fatigue constants was analyzed using both statistical theory and a Monte Carlo computer simulation technique. It was found that the statistical reproducibility depended not only on the number of test samples but also on the other...

Hotelling's T-square procedure for testing the significance of a mean vector treats all variables symmetrically and may not be appropriate if the variables carry unequal importance. The step-down procedure, a possibly appropriate alternative, is studied in this paper. An underlying invariance structure is established and then used to develop a canonical form for studying the power functions of the two methods. A Monte Carlo experiment is conducted in this framework and conclusions are reported.

In this paper we present a unified framework for simulating Markovian models of highly dependable systems. Since the failure event is a rare event, the estimation of system dependability measures using standard simulation requires very long simulation runs. We show that a variance reduction technique called Importance Sampling can be used to speed up the simulation by many orders of magnitude over standard simulation. This technique can be combined very effectively with regenerative simulation...

Work completed under this grant on polar fluids includes an extension of perturbation theory to polar molecules with point octopoles and hexadecapoles as well as a preliminary investigation of molecules with non-spherical cores. In addition, the ordering of dipolar molecules near a flat electrified wall has been investigated in the linearized hypernetted chain (LHNC) and quadratic hypernetted chain (QHNC) approximations. This has led to a new study of electrostriction and non-linear effects in...

Estimating component reliabilities along with the system reliability frequently requires using lifetimes from the system level. Due to cost and time constraints, however, the exact cause of system failure may be unknown. Instead, it may only be ascertained that the cause of failure is due to one component in a subset of components, e.g., the subset forms a subsystem. Confronted with such data, this article discusses how to exploit fully the available information using a maximum likelihood...

The bootstrap estimator of the asymptotic covariance matrix of a function of sample means or sample quantiles is inconsistent in some situations. A modified bootstrap estimator is proposed and shown to be consistent under weak conditions. A simulation study shows that in terms of finite-sample performance, the improvement of this modification is substantial. The computation of this modified bootstrap estimator is much easier and cheaper than that of the estimator based on the quantiles of the...

A method for estimating the present failure rate of a program is presented. A crude nonparameter estimate of the failure rate function is obtained from past failure times. This estimate is then smoothed by fitting a completely monotonic function, which is the solution of a quadratic programming problem. The value of the smoothed function at present time is used as the estimate of present failure rate. Results of a Monte Carlo study of performance are given.

We consider the theory of chemisorption on stepped surfaces for systems for which a lattice gas in thermodynamic equilibrium is an appropriate model. Using statistical mechanics we demonstrate that by comparing LEED (Low Energy Electron Diffraction) results for flat and stepped substrates one can determine the change in adsorption energy at terrace edges. Thus one can answer the important question of whether adatoms bind more or less strongly at this kind of defect site. We also examine some...

Binary response models are used in estimating the probability, P(x), of a successful response when an experimental unit is exposed to a stimulus level, x. Frequently, the aim of the investigator is to locate a specific level of stimulus for which P(x) takes on a known value, p. The stimulus level sought, X sub 100 p, is referred to as the P sub th quantile of P(x). When p lies outside the interval (.25,.75), X sub 100 p is considered to be an extreme quantile.
