Alternative Confidence Interval for Variability Parameters in the Normal Distribution with Applications to Stock Exchange Index Data Set

open access: yesAustrian Journal of Statistics, 2023
This work focusses on estimation the standard deviation (SD) and coefficient of variation (CV) in the normal distribution. These two measures are useful in applications and widely used to report the spread or variability of continuous data.

Random walk in Markovian environment

open access: yes, 2008
We prove a quenched central limit theorem for random walks with bounded increments in a randomly evolving environment on $\mathbb{Z}^d$. We assume that the transition probabilities of the walk depend not too strongly on the environment and that the ...

Angewandte Geostatistik in der landwirtschaftlichen Versuchsplanung

open access: yesAustrian Journal of Statistics, 2016
In der landwirtschaftlichen Versuchsplanung tritt oft auch eine räumliche und/oder eine zeitliche Komponente auf. Bei Feldversuchen mit raumbezogenen Daten kann die Variation zwischen Messungen bei einer bestimmten Distanz mit Hilfe des Semivariogramms ...

On the P-value for Members of the Cressie-Read Family of Divergence Statistics

open access: yesAustrian Journal of Statistics, 2023
A few years ago a paper appeared in this Journal that proposed a closed-form approximation of the p-value for Pearson's chi-squared statistic. Extensive empirical and simulation studies were performed and it was shown that the approximation provides ...

Evaluating normal probabilities on a graphics calculator [PDF]

open access: yes, 2001
One of the strengths of a graphics calculator is the potential it offers for students to explore mathematical ideas from a few different perspectives. A good example of this involves the normal probability distribution, frequently encountered in senior ...

Minimax signal detection in ill-posed inverse problems

open access: yes, 2012
Ill-posed inverse problems arise in various scientific fields. We consider the signal detection problem for mildly, severely and extremely ill-posed inverse problems with $l^q$-ellipsoids (bodies), $q\in(0,2]$, for Sobolev, analytic and generalized ...

Extracting Information from Interval Data Using Symbolic Principal Component Analysis

open access: yesAustrian Journal of Statistics, 2017
We introduce generic definitions of symbolic variance and covariance for random interval-valued variables, that lead to a unified and insightful interpretation of four known symbolic principal component estimation methods: CPCA, VPCA, CIPCA, and ...

Analysis of Count Time Series: A Bayesian GARMA(p, q) Approach

open access: yesAustrian Journal of Statistics, 2023
Extensions of the Autoregressive Moving Average, ARMA(p, q), class for modeling non-Gaussian time series have been proposed in the literature in recent years, being applied in phenomena such as counts and rates.

Confidence bands in nonparametric time series regression

open access: yes, 2008
We consider nonparametric estimation of mean regression and conditional variance (or volatility) functions in nonlinear stochastic regression models.

Industrial Statistics Revisited: From Footnotes to Meta-Information Management

open access: yesAustrian Journal of Statistics, 2016
UNIDO maintains a long tradition in the compilation of international statistics on industrial production and, particularly, has developed a suite of tools and techniques for improving third-party data, mainly supplied directly or indirectly by National ...
