Statistical analysis of astro-geodetic data through principal component analysis, linear modelling and bootstrap based inference

Autor: Gornea, Andreea Ioana, Calin, Alexandru, Dumitru, Paul Daniel, Nedelcu, Dan Alin, Stoica, Radu Stefan

The paper demonstrates the application of statistical based methodology for the analysis of the vertical deviation angle. The studied data set contains astro-geodetic observations. The Principal Component Analysis and the Multiple Linear Regression m

Level sets estimation and Vorob'ev expectation of random compact sets

Autor: Heinrich, Philippe, Stoica, Radu Stefan, Tran, Viet Chi

Publikováno v: spatial statistics 2 (2012) 47-61

The issue of a "mean shape" of a random set $X$ often arises, in particular in image analysis and pattern detection. There is no canonical definition but one possible approach is the so-called Vorob'ev expectation $\E_V(X)$, which is closely linked t

Species persistence decreases with habitat fragmentation: an analysis in periodic stochastic environments. Research report

Autor: Roques, Lionel, Stoica, Radu Stefan, Institut National de la Recherche Agronomique UR 0546 Biostatistique et Processus Spatiaux

Publikováno v: Species persistence decreases with habitat fragmentation: an analysis in periodic stochastic environments. Research report, 23(2006)

This paper presents a study of a nonlinear reaction-diffusion population model in fragmented environments. The model is set on RN, with periodic heterogeneous coefficients obtained using stochastic processes. Using a criterion of species persistence
