Primordial Statistical Anisotropies: The Effective Field Theory Approach

, 2015
In this work we present the effective field theory of primordial statistical anisotropies generated during anisotropic inflation involving a background $U(1)$ gauge field.

Statistical tests, P values, confidence intervals, and power: a guide to misinterpretations

European Journal of Epidemiology, 2016
Misinterpretation and abuse of statistical tests, confidence intervals, and statistical power have been decried for decades, yet remain rampant. A key problem is that there are no interpretations of these concepts that are at once simple, intuitive ...

Afterglow Light Curves and Broken Power Laws: A Statistical Study

, 2006
In gamma-ray burst research it is quite common to fit the afterglow light curves with a broken power law to interpret the data. We apply this method to a computer simulated population of afterglows and find systematic differences between the known model ...

A Systematic Review on the Evolution of Power Analysis Practices in Psychological Research

Psychologica Belgica
Performing hypothesis tests with adequate statistical power is indispensable for psychological research. In response to several large-scale replication projects following the replication crisis, concerns about the root causes of this crisis – such as ...

Kinetic power of quasars and statistical excess of MOJAVE superluminal motions

, 2012
The MOJAVE survey contains 101 quasars with a total of 354 observed radio components that are different from the radio cores, among which 95% move with apparent projected superluminal velocities with respect to the core, and 45% have projected velocities

Evaluation of autumn mist‐netting data for monitoring passerine populations in interior Alaska

Wildlife Society Bulletin, 2012
We evaluated the data from 2 autumn mist‐netting stations for monitoring passerine population trends and measuring the timing of migration. Migration‐monitoring stations were operated during autumn from 1993 to 2009 at 2 interior Alaska locations: in ...

Models, Methods and Network Topology: Experimental Design for the Study of Interference

, 2018
How should a network experiment be designed to achieve high statistical power? Ex- perimental treatments on networks may spread. Randomizing assignment of treatment to nodes enhances learning about the counterfactual causal effects of a social network ...

The relationship between statistical power and predictor distribution in multilevel logistic regression: a simulation-based approach

BMC Medical Research Methodology, 2019
BackgroundDespite its popularity, issues concerning the estimation of power in multilevel logistic regression models are prevalent because of the complexity involved in its calculation (i.e., computer-simulation-based approaches).

Angular-planar CMB power spectrum

, 2009
Gaussianity and statistical isotropy of the Universe are modern cosmology's minimal set of hypotheses. In this work we introduce a new statistical test to detect observational deviations from this minimal set.
