Statistical Power in Longitudinal Network Studies [PDF]

, 2017
Longitudinal social network studies can easily suffer from insufficient statistical power. Studies that simultaneously investigate change of network ties and change of nodal attributes (selection and influence studies) are particularly at risk because ...

Impacts on study design when implementing digital measures in Parkinson's disease-modifying therapy trials

Frontiers in Digital Health
IntroductionParkinson's Disease affects over 8.5 million people and there are currently no medications approved to treat underlying disease. Clinical trials for disease modifying therapies (DMT) are hampered by a lack of sufficiently sensitive measures ...

Statistical power: An historical introduction [PDF]

Tutorials in Quantitative Methods for Psychology, 2007
Despite the funding agencies’ growing demands towards power analyses, we believe researchers are still not fully aware of the statistical power concept, of the possible benefits of power analysis in the planning phase and of the ways to increase the ...

Self-organization of structures and networks from merging and small-scale fluctuations

, 2004
We discuss merging-and-creation as a self-organizing process for scale-free topologies in networks. Three power-law classes characterized by the power-law exponents 3/2, 2 and 5/2 are identified and the process is generalized to networks.

Partial least squares regression can aid in detecting differential abundance of multiple features in sets of metagenomic samples

Frontiers in Genetics, 2015
It is now feasible to examine the composition and diversity of microbial communities (i.e., `microbiomes‘) that populate different human organs and orifices using DNA sequencing and related technologies.

Macroscopic thermodynamics of equilibrium characterized by power-law canonical distributions

, 2000
Macroscopic thermodynamics of equilibrium is constructed for systems obeying power-law canonical distributions. With this, the connection between macroscopic thermodynamics and microscopic statistical thermodynamics is generalized.

A statistical model for the excitation of cavities through apertures

, 2015
In this paper, a statistical model for the coupling of electromagnetic radiation into enclosures through apertures is presented. The model gives a unified picture bridging deterministic theories of aperture radiation, and statistical models necessary for

Quantumlike Chaos in the Frequency Distributions of the Bases A, C, G, T in Drosophila DNA [PDF]

, 2002
Continuous periodogram power spectral analyses of fractal fluctuations of frequency distributions of bases A, C, G, T in Drosophila DNA show that the power spectra follow the universal inverse power-law form of the statistical normal distribution ...

Statistical properties of power-law random banded unitary matrices in the delocalization-localization transition regime

, 2012
Power-law random banded unitary matrices (PRBUM), whose matrix elements decay in a power-law fashion, were recently proposed to model the critical statistics of the Floquet eigenstates of periodically driven quantum systems.
