Variances and Covariances in Deconvolution
نویسنده
چکیده
This paper discusses some aspects of deconvolution of one-dimensional spectra in the framework of the Least Squares Method and presents a minimum variance regularization procedure. Covariance matrices are taken into account in every step. Fluctuation and artifacts, both in the deconvolved and regularized spectra, are related to the structure of the covariance matrices. The method is applied to a simulated spectrum and to the S ( ; xn ) cross section determination from actual yield data.

Mean and covariance matrix adaptive estimation for a weakly stationary process. Application in stochastic optimization
We introduce an adaptive algorithm to estimate the uncertain parameter of a stochastic optimization problem. The procedure estimates the one-step-ahead means, variances and covariances of a random process in a distribution-free and multidimensional framework when these means, variances and covariances are slowly varying on a given past interval. The quality of the approximate problem obtained w...
متن کاملVariance and covariances of the numbers of synonymous and nonsynonymous substitutions per site.
Nei and Gojobori (1986) developed a simple method to estimate the numbers of synonymous (ds) and nonsynonymous (dN) substitutions per site. In the present paper, we have developed a method for computing variances and covariances of ds's and dN's and of the proportions of synonymous (ps) and nonsynonymous (pN) differences. We also have developed a method for computing the variances of mean dS, d...
متن کاملVariances and covariances of identity coefficients of a multigene family.
By using a model of gene conversion for treating concerted evolution of multigene families, a theory for calculating the variances and covariances of identity coefficients has been developed. Six coefficients on triple identity and 15 coefficients on quadruple identity are needed. The variances and covariances are obtained from the quadruple identity coefficients and divided into within-populat...

A numerical method is developed for accurately approximating head and ̄ux covariances and cross-covariances in ®nite twoand three-dimensional domains using the mixed ®nite element method. The method is useful for determining head and ̄ux covariances for non-stationary ̄ow ®elds, for example those induced by injection or extraction wells, impermeable subsurface barriers, or non-stationary hydraulic...
متن کاملGeneralized Roe and Metz receiver operating characteristic model: analytic link between simulated decision scores and empirical AUC variances and covariances.
Modeling and simulation are often used to understand and investigate random quantities and estimators. In 1997, Roe and Metz introduced a simulation model to validate analysis methods for the popular endpoint in reader studies to evaluate medical imaging devices, the reader-averaged area under the receiver operating characteristic (ROC) curve. Here, we generalize the notation of the model to al...
