On the density of the sum of two independent Student t-random vectors

Berg, C.; Vignat, C. - In: Statistics & Probability Letters 80 (2010) 13-14, pp. 1043-1055

In this paper, we find an expression for the density of the sum of two independent d-dimensional Student t-random vectors and with arbitrary degrees of freedom. As a byproduct we also obtain an expression for the density of the sum , where is normal and is an independent Student t-vector. In...

Fuzzy and rule-based image convolution

Looney, Carl G. - In: Mathematics and Computers in Simulation (MATCOM) 51 (2000) 3, pp. 209-219

An image can be sharpened by high pass filtering of its discrete Fourier transform or by an equivalent convolution … taken here to sharpening and edge detection, as well as smoothing and other processing is to use a ‘smart’ convolution mask … that makes rule-based decisions. Upon employing gains in the rule consequents, we achieve a type of fuzzy convolution of …

A generalization of histogram type estimators

Delicado, Pedro; Río, Manuel del - Department of Economics and Business, Universitat … - 1999

We introduce simple nonparametric density estimators that generalize the classical histogram and frequency polygon. The new estimators are expressed as linear combination of density functions that are piecewise polynomials, where the coefficients are optimally chosen in order to minimize the...

Neighborhoods as nuisance parameters? Robustness vs. semiparametrics

Rieder, Helmut - 1999

Deviations from the center within a robust neighborhood may naturally be considered an infinite dimensional nuisance parameter. Thus, in principle, the semiparametric method may be tried, which is to compute the scores function for the main parameter minus its orthogonal projection on the closed...
