Semiparametric Estimation of Index Coefficients

Econometrica, 1989
This paper gives a solution to the problem of estimating coefficients of index models, through the estimation of the density-weighted average derivative of a general regression function. The estimators, based on sample analogues of the product moment representation of the average derivative, are constructed using nonparametric kernel estimators of the ...

On estimation of discriminant coefficients

Statistics & Probability Letters, 1991
Abstract Estimation of discriminant coefficients arises in linear discriminant analysis when the Fisher's linear discriminant function is viewed as the posterior log-odds. Accordingly, we treat the problem of estimating the discriminant coefficients under the quadratic loss. We obtain a class of improved estimators dominating the ‘unbiased’ estimator,

Estimate of interactive coefficients

2009 8th International Conference on Reliability, Maintainability and Safety, 2009
Engineering assets are often complex systems. In a complex system, components often have failure interactions which lead to interactive failures. A system with interactive failures may lead to an increased failure probability. Hence, one has to take the interactive failures into account when designing and maintaining complex engineering systems.

Estimating Wavelet Coefficients

1995
We consider fast algorithms of wavelet decomposition of functionf when discrete observations of \( f(\operatorname{supp} f \subseteq [0,1]) \) are available. The properties of the algorithms are studied for three types of observation design: the regular design, when the observationsf(x i) are taken on the regular grid \( {{\chi }_{i}} = i/N,i = 1 ...

Estimation of Fourier coefficients

IEEE Transactions on Instrumentation and Measurement, 1989
It is shown that the maximum-likelihood estimation or robust estimation of the Fourier coefficients may be preferable to Fourier transformation if the noise contains outliers or is otherwise not normally distributed. The reason is that, in that case, these estimators produce Fourier coefficient estimates and, therefore, system parameter estimates ...

Estimates for the Connection Coefficients

2003
We consider Hodge systems of equations defined on a compact two-dimensional Riemann surface. We recall Definition 3.1.4 of Chapter 3.
