Estimation of Variance of the Ratio Estimator

Biometrika, 1982
SUMMARY A general class of estimators of the variance of the ratio estimator is considered, which includes two standard estimators vo and v2 and approximates another estimator VH suggested by Royall & Eberhardt (1975). Asymptotic expansions for the variances and biases of the proposed estimators are obtained.

On the Estimation of Contrasts in Linear Estimation

Calcutta Statistical Association Bulletin, 1973
This paper examines the conditions on the coefficient matrix of the linear model under which contrasts, and contrasts alone, are estimated by contrasts.

Estimation of the MSE matrix of the stein estimator

Canadian Journal of Statistics, 1988
Uniformly minimum-variance unbiased (UMVU) estimators of the total risk and the mean-squared-error (MSE) matrix of the Stein estimator for the multivariate normal mean with unknown covariance matrix are proposed. The estimated MSE matrix is helpful in identifying the components which contribute most to the total risk. It also contains information about

Kalman-based estimator for DOA estimations

IEEE Transactions on Signal Processing, 1994
We introduce a new Kalman-based noise-subspace estimator combined with the Root-MUSIC for direction of-arrival (DOA) estimation of uncorrelated narrow-band plane waves impinging on an array of sensors. Without both a priori knowledge of the number of sources and the inflation method presented by Yang and Kaveh (1988), we show that the Kalman-based ...

A minimum discrepancy estimator in parameter estimation

IEEE Transactions on Information Theory, 1998
Summary: In statistical estimation theory, a satisfactory estimator should be able to embody a large portion of the available information, which may be known a priori or provided by the data. Hence, the loss of information is minimum when this estimator is employed.

Estimability and estimation of excess and etiologic fractions

Statistics in Medicine, 1989
AbstractThis paper describes conditions under which epidemiologic data can provide estimates of the excess fraction (proportionate increase in caseload due to an exposure) and the etiologic fraction (fraction of cases caused by exposure). The excess fraction can be estimated under essentially the same conditions often cited for general study validity ...
