Estimating and testing variance components in a multi-level GLM
Most analysis of multi-subject fMRI data is concerned with determining whether there exists a significant population-wide 'activation' in a comparison between two or more conditions. This is typically assessed by testing the average value of a contrast of parameter estimates (COPE) against zero in a general linear model (GLM) analysis. However, important information can also be obtained by test...
متن کاملEfficient lα Distance Approximation for High Dimensional Data Using α-Stable Projection
In recent years, large high-dimensional data sets have become commonplace in a wide range of applications in science and commerce. Techniques for dimension reduction are of primary concern in statistical analysis. Projection methods play an important role. We investigate the use of projection algorithms that exploit properties of the α-stable distributions. We show that lα distances and quasi-d...
متن کاملEstimators and tail bounds for dimension reduction in lα (0 < α ≤ 2) using stable random projections
Abstract The method of stable random projections is popular in data stream computations, data mining, information retrieval, and machine learning, for efficiently computing the lα (0 < α ≤ 2) distances using a small (memory) space, in one pass of the data. We propose algorithms based on (1) the geometric mean estimator, for all 0 < α ≤ 2, and (2) the harmonic mean estimator, only for small α (e...

متن کاملLamellar Lα mesophases doped with inorganic nanoparticles.
The development of nanostructured hybrid systems is a flourishing area of research, which brings together chemistry, physics and materials science. These systems are composed of nanoparticles with interesting properties (e.g. optical, magnetic, catalytic) dispersed within an organic matrix. Control of both the position and orientation of the particles in a precise and reproducible way is an imp...
