|
| Suppose we observe the sum of two independent random variables X and Z, where Z denotes measurement error and has a known distribution, and where the unknown density f of X is to be estimated. It is shown that if Z is normally distributed and if f has k bounded derivatives, then the fastest attainable convergence rate of any nonparametric estimator of f is only (log n)-k/1. Therefore deconvolution with ... |

| An Asymptotic Theory for Weighted Least Squares with Weights Estimated by Replication |
AUG 88 |
19 pages |
| Authors:
Raymond J. Carroll; Daren B. Cline; TEXAS A AND M UNIV COLLEGE STATION
|
| This document considers a heteroscedastic linear regression model with replication. To estimate the variances, one can use the sample variances or the sample average squared errors from a regression fit. The authors study the large sample properties of these weighted least squares estimates with estimated weights when the number of replicates is small. The estimates are generally inconsistent for asymmetrically distributed data. If sample variances are used based on m ... |

| Authors:
R. J. Carroll; J. Sacks; C. H. Spiegelman; TEXAS A AND M UNIV COLLEGE STATION
|
| The standard multiple use calibration procedure due to Scheffe (1973) states that with probability 1-delta, the proportion of calculated confidence intervals containing the true unknowns is at least 1-alpha in the long run. The probability 1-delta refers to the probability that the calibration experiment results in a 'good' outcome. In Scheffe's formulation a good outcome involves both coverage of the true underlying regression curve and an upper confidence limit for ... |

| Variance Function Estimation in Regression: The Effect of Estimating the Mean |
AUG 88 |
18 pages |
| Authors:
Peter Hall; R. J. Carroll; TEXAS A AND M UNIV COLLEGE STATION
|
| The authors consider estimation of a variance function g in regression problems. Such estimation requires simultaneous estimation of the mean function f. We obtain sharp results on the extent to which the smoothness of f influences best rates of convergence for estimating g. For example, in nonparametric regression with two derivatives on g, classical rates of convergence are possible if and only if the unknown f satisfies a Lipschitz condition ... |

| Authors:
M. Davidian; R. J. Carroll; W. Smith; TEXAS A AND M UNIV COLLEGE STATION
|
| Assay data are often fitted by a nonlinear regression model incorporating heterogeneity of variance. Typically, the standard deviation of the response is taken to be proportional to a power Theta of the mean. There is considerable empirical evidence suggesting that for assays of a resonable size, how one estimates the parameter Theta does not greatly affect how well one estimates the mean regression function. An additional component of assay analysis ... |

| Authors:
J. L. Junkins; R. C. /Thompson; TEXAS A AND M UNIV COLLEGE STATION
|
| A quasianalytical method is presented for solving nonlinear, open-loop, optimal control problems. The approach combines a simple analytical, straightforward expansion from perturbation methods with powerful numerical algorithms to solve a series of nonhomogeneous, linear, optimal control problems. In the past, the only recourse for solving such nonlinear problems relied almost exclusively on iterative numerical methods, whereas the asymptotic perturbation approach may produce accurate solutions to nonlinear problems without iteration.

Robert A. Arnone; Robert R. Bidigare; Charles C. Trees; J. M. Brooks; TEXAS A AND M UNIV COLLEGE STATION
|
| Spectral irradiance and pigment (porphyrin and carotenoid) measurements were made across strong frontal boundaries of the Gulf Stream in the northwest Atlantic. Upwelling and downwelling irradiance were measured at 2- nanometer (nm) increments across the visible spectrum (400-700 nm). Pigment concentration were determined by high performance liquid chromatography (HPLC). The irradiance spectra suggest that passive fluorescence occurs in frontal waters. The phytoplankton pigment composition showed significant changes across the frontal ... |

| Authors:
A. L. Highsmith; K. L. Reinfsnider; TEXAS A AND M UNIV COLLEGE STATION
|
| Two fundamental processes govern the reduction of strength and stiffness of composite laminates caused by cyclic loading, commonly called the fatigue effect. One process is the reduction of the strength and stiffness of the individual constituent materials in the composite, caused by events such as localized nonconservative deformation, microcrack formation, and substructure variations. This process is essentially the source of the fatigue effect homogeneous materials, except that macrocrack formation and ... |

C. D. Fisher; J. B. Shaw; R. W. Woodman; TEXAS A AND M UNIV COLLEGE STATION
|
| Organizations continuously bring in new recruits or employees and move employees to new positions, units, and/or locations. With these transitions comes the need for the individual to learn and adapt to the new role requirements. The organization must provide means for communicating and reinforcing the role requirements and, within limits, adapting to the new member. This learning-communicating-adapting process is what is meant by the socialization process. To the extent the ... |

| Authors:
A. L. Highsmith; K. L. Reifsnider; TEXAS A AND M UNIV COLLEGE STATION
|
| The study of delamination in composite laminates has, for the most part, been centered around the problem of interlaminar stresses associated with edges of coupon specimens subjected to in-plane loading. The appeal of this problem to the analyst has to do with the applicability of linear elastic fracture mechanics to the description of delamination growth and initiation. In actuality, delamination rarely occurs as an independent damage mode. When it is ... |

|
| Several common diseases of coastal fishes should play an important role in aquacultures that utilize dredged material containment sites. Circumstances that develop from increased stock density should favor crustacean parasites and parasites with simple life cycles. Climate extremes and abrupt changes are apt to predispose microbial disease and water enrichment will favor oxygen shortage and epiboint fouling. Potential corrective measures are noted. (Author) |

| Compactly supported spline-wavelets are used to process simulated transient signals in a noisy environment. It is found that linear-phase spline- wavelets can be effectively used as near-optimal time-domain windows to localize the signal onsets. This technique does not require the a priori knowledge of the signal. Results are demonstrated numerically by the detection of signal arrivals in noise. |

| The generalizability of the correlates of organizational commitment is examined using two definitions of commitment. Personal, job, organizational, and labor market variables are examined in relation to organizational commitment and employee turnover. Results for Taiwan workers are generally similar to published studies of U.S. and Japanese workers, with some exceptions. The definition of organizational commitment does make a difference. Implications for commitment and turnover research are discussed. (Author) |
