This study examined the problem of interpreting effect sizes in single case research. Nine single case analytic techniques were applied to a convenience sample of 77 published interrupted time series (AB) datasets, and the results were compared by technique across the datasets. Reanalysis of the ...
It is known that the Wilcoxon-Mann-Whitney test is strongly influenced by unequal variances of treatment groups combined with unequal sample sizes. This simulation study indicates that, for various continuous and discrete distributions, the discrepancy between the empirical Type I error rate and the ...

public hydrological datasets that have been used for hydrological research–for example, datasets used by Becket al.32,33, for global model calibration or by Blöschlet al.34for extrapolating climate change impacts on flooding (less than a third of one percent of the daily time series used in...
LARGE SAMPLE TESTS FOR COMPARING REGRESSION COEFFICIENTS IN MODELS WITH NORMALLY DISTRIBUTED VARIABLES The goal of the simulations is to check the distributions of the three statistics for finite sample sizes and at a stationary point of the null hypothesis... AAV Davier - 《Ets Research Report》 ...
It may be that medical-related fields have a stronger level of proof embedded in their research culture. Physics had the lowest re-execution rate, though due to the low sample size and the fact that Dataverse is probably not the repository of choice in physics, we cannot draw conclusions ...
on age-related changes, understanding of the general age-related function of real-life performance, as well as the factors that change this function, has proved elusive. We believe that this is due to two main reasons: the difficulty of obtaining large sample sizes of measurements in real-...
The Pearson correlation coefficients were 0.51 for the former task (can increase to 0.61 when only counties with large sample sizes are included) and − 0.36 for the latter task (can increase to − 0.47 when only counties with large sample sizes are included). We acknowledge that the ...
heterogeneities in allelic effects between studies, we also performed “trans-ethnic meta-analysis” using MANTRA25in the replication sample that included all ethnic groups (“Rep-All”) and in the combined analysis of the discovery and all ethnic groups in the replication sample (“Combined All”...
(Table2). The best model according to Akaike’s Information Criterion for finite sample sizes (AICc)41takes the form: labyrinth size ~ Skull box volume + forelimbs not-webbed (AICc weight = 0.152;R2 = 0.897; Table2). The coefficient of ‘forelimbs not-webbed’ in this ...
