Discussion of: A statistical analysis of multiple temperature proxies: Are reconstructions of surface temperatures over the last 1000 years reliable?
reconstructions of surface temperatures statistical analysis paleoclimate reconstructions

As McShane and Wyner (2011) observe, there are formidable statistical
problems in “reconstructing” past temperatures from networks of so-called
“proxy” data with weak “signal” and complicated autoco...

This article (MW) has stimulated much valuable discussion and helped to
focus attention on an important area for the application of statistics. Given
the short amount of space, however, we reluctant...
Conformal geometry of statistical manifold with application to sequential estimation
Affi ne connections Curved exponential family Hyperboloid dis-tribution Information geometry Projective transformation Riemannian metric Space of constant curvature Totally umbilic von Mises-Fisher distribution

Technology has had an unquestionable impact on the way people watch sports. As technology has evolved, so too has the knowledge of a casual sports fan. A direct result of this evolution is the amount ...
Randomized algorithms for statistical image analysis and site percolation on square lattices
Image analysis signal detection percolation image reconstruction noisy image
2011/3/24
We propose a novel probabilistic method for detection of objects in noisy images. The method uses results from percolation and random graph theories. We present an algorithm that allows to detect obje...

In the series of our earlier papers on the subject, we proposed a novel statistical hypothesis testing method for detection of objects in noisy images. The method uses results from percolation theory ...
Statistical analysis of $k$-nearest neighbor collaborative recommendation
Collaborative recommendation cosine-type similarity
