Improving PSF calibration in confocal microscopic imaging---estimating and exploiting bilateral symmetry
confocal microscopic imaging PSF calibration estimating exploiting bilateral symmetry
2011/3/18
A method for estimating the axis of reflectional symmetry of an image $f(x,y)$ on the unit disc $D=\{(x,y):x^2+y^2\leq1\}$ is proposed, given that noisy data of $f(x,y)$ are observed on a discrete gri...
Bounding and estimating an exceedance probability in output from monotonous computer codes
Statistics Theory (math.ST) Methodology (stat.ME)
2010/12/17
This article deals with the estimation of a probability p of an undesirable event. Its occurence is formalized by the exceedance of a threshold reliability value by the unidimensional output of a (tim...

Estimating discontinuous periodic signals in a non-time homogeneous diffusion process
diffusions inhomogeneity in time discontinuous signal periodicity limit theorems likelihood ratio processes
2010/3/19
We consider a diffusion (t)t0 with some T -periodic time dependent input term contained in the drift: under an unknown parameter # 2 , some discontinuity – an additional periodic signal – occurs at...
Estimating Bayesian Networks for High-dimensional Data with Complex Mean Structure
Bayesian networks complex mean structure high-dimensionaldata regulatory networks
2010/3/10
The estimation of Bayesian networks given high-dimensional data sets,
in particular given gene expression data sets, has been the focus of much
recent research. While there are many methods availabl...
Optimal rates of convergence for estimating the null density and proportion of nonnull effects in large-scale multiple testing
Optimal rates convergence null density proportion nonnull effects large-scale multiple testing
2010/3/9
An important estimation problem that is closely related to largescale
multiple testing is that of estimating the null density and the
proportion of nonnull effects. A few estimators have been introd...
