How to keep the Type I Error Rate in ANOVA if Variances are Heteroscedastic

Karl Moder

Austrian Journal of Statistics, Vol. 36 No. 3 · 2016 · Inggris · DOAJ Scopus

One essential prerequisite to ANOVA is homogeneity of variances in underlying populations. Violating this assumption may lead to an increased type I error rate. The reason for this undesirable effect is due to the calculation of the corresponding F-value. A slightly different test statistic keeps…

Predictors for residential mobility in later life: Empirical findings for the young-old living in an Austrian small town

Tatjana Fischer; Markus Jobst; Karl Moder

Acta Geographica Slovenica, Vol. 65 No. 1 · 2025 · Slovenia · DOAJ Scopus

The article addresses residential mobility in later life from the perspective of the young-old, an under-explored topic in Austria. Data originating from a written survey conducted as part of a cross-sectional case study on people aged 60 to 74 years living in an Austrian small town are used to…

Potential of ten alternative grass species under different cutting regimes in Central Europe

Josef Schrabauer; Karl Buchgraber; Karl Moder dkk.

Journal für Kulturpflanzen, Vol. 66 No. 6 · 2014 · Inggris · DOAJ Scopus

Perennial grasslands play an important role as an extensive CO2 sink. Fodder and biofuels can be produced in an ecologically acceptable manner on such sites. Projected future climate-change scenarios suggest that Central Europe’s grasslands will be increasingly affected by drought. In order to…

Allele Intersection Analysis: A Novel Tool for Multi Locus Sequence Assignment in Multiply Infected Hosts

Wolfgang Arthofer; Markus Riegler; Hannes Schuler dkk.

PLoS ONE, Vol. 6 No. 7 · 2011 · Inggris · PLOS Scopus

Wolbachia are wide-spread, endogenous α-Proteobacteria of arthropods and filarial nematodes. 15–75% of all insect species are infected with these endosymbionts that alter their host's reproduction to facilitate their spread. In recent years, many insect species infected with multiple Wolbachia…

Kinetics of lead release from soils at historic mining and smelting sites, determined by a modified electro-ultrafiltration

Anto Jelecevic; Dietmar Horn; Herbert Eigner dkk.

Plant, Soil and Environment, Vol. 65 No. 6 · 2019 · Inggris · DOAJ Scopus

Within a pilot study, after pedological and mineralogical characterization, various kinetic models were tested to fit lead (Pb)-mobilization kinetics from soils at historic mining and smelting sites. Pb mobilization was obtained by modified electro-ultrafiltration (EUF) after addition of…

A near-infrared spectroscopy routine for unambiguous identification of cryptic ant species

Martin-Carl Kinzner; Herbert C. Wagner; Andrea Peskoller dkk.

PeerJ, Vol. 3 · 2015 · Inggris · DOAJ Scopus

Species identification—of importance for most biological disciplines—is not always straightforward as cryptic species hamper traditional identification. Fibre-optic near-infrared spectroscopy (NIRS) is a rapid and inexpensive method of use in various applications, including the identification of…

Clarification of local causes for lesser horseshoe bat extinction in the Bavarian-Tyrolean Alpine region

Cornelia Röß; Anton Vorauer; Andreas Zahn dkk.

Global Ecology and Conservation, Vol. 58 · 2025 · Inggris · DOAJ Scopus

Once widespread in Europe, the lesser horseshoe bat (Rhinolophus hipposideros) suffered massive population declines in the second half of the 20th century and became extinct in some countries. For future conservation programs, it is important to understand the major causes of extinction. Here, we…
