Analytic Determination of Scaling Parameters

2006 IEEE International Symposium on Information Theory, 2006
We show that the finite-length scaling parameters for irregular LDPC codes when used over the binary erasure channel can be computed without resorting to "covariance evolution". We provide simple expressions that can be evaluated using solely the degree distributions and the characteristics of the fixed point of density evolution.

Linear estimates of a population scale parameter

Biometrika, 1967
SUMMARY Downton (1966) proposed an estimator, u*, for o-, the standard deviation of a normal population. This estimator is a simple linear combination of the order statistics of a sample from the population. In the present paper, four moments of o-* are given in closed form and the use of Y = (,c6-,uO)/o* is investigated as a possible competitor to the

Two-parameter scaling in the Wigner ensemble

Physical Review Letters, 1993
The Wigner ensemble of band random matrices describes the statistical properties of strongly chaotic Hamiltonians; it may also be viewed as a disordered tight-binding model with an electric field. We investigate the scaling properties of the localization of eigenstates and that of the distribution of level spacings, P(s), for finite matrices.

On the Simultaneous Estimation of Scale Parameters

Canadian Journal of Statistics, 1988
This note is an extension of \textit{A. DasGupta}'s results [Ann. Stat. 14, 206-219 (1986; Zbl 0602.62011)] on the estimation of multiparameter gamma distributions. Consider p(p\(\geq 2)\) independent positive random variables with possibly different scale-parameter densities.

Scaling parameter and universality

Physica, 1972
Abstract Scaling laws and universality with respect to a parameter are derived from the same standpoint. An equation of state for small values of the parameter is found, which has the property of homogeneity and universality, and also describes systems which for some value of the parameter change critical behaviour.
