Statistical origin of allometry
The allometry relationship (AR) between two properties of a living network X and Y is X = aY b where one or both of the variables is a measure of size and the allometry coefficient a and exponent b are fit to data. Many investigators have focused on determining the proper value of b entailed by an appropriate biological model, whereas others have argued that the allometry coefficient plays the ...
متن کاملAutomated Statistical Thresholding for EEG artifact Rejection
Electroencephalogram (EEG) data are typically contaminated with artifacts (e.g., by eye movements). The effect of artifacts can be attenuated by deleting data with amplitudes over a certain value, for example. Independent component analysis (ICA) separates EEG data into neural activity and artifact; once identified, artifactual components can be deleted from the data. Often, artifact rejection ...
متن کاملImagination inflation: a statistical artifact of regression toward the mean.
In the imagination inflation procedure of Garry, Manning, Loftus, and Sherman (1996), subjects rated a list of events in terms of how likely each was to have occurred in their childhood. Two weeks later, some of the events were imagined; control events were not. The subjects then rated the likelihood of occurrence for each event a second time. Garry et al. (1996) reported that the act of imagin...
متن کاملStochastic Ontogenetic Allometry: The Statistical Dynamics of Relative Growth
BACKGROUND In the absence of stochasticity, allometric growth throughout ontogeny is axiomatically described by the logarithm-transformed power-law model, θt = log(a) b + kφ(t), where θt ≡ θ(t) and φt ≡ φ(t) are the logarithmic sizes of two traits at any given time t. Realistically, however, stochasticity is an inherent property of ontogenetic allometry. Due to the inherent stochasticity in bot...
متن کاملIntra-Industry Trade in a Loglinear Model∗
Within the framework of an n-commodity, n-factor, K-country loglinear model with identical Cobb–Douglas production coefficients and identical consumer-expenditure shares across countries, balanced trade, and a pattern of world endowments permitting positive outputs of all commodities in each country, it is shown that, given any mode of aggregating the n commodities into at most n − 1 industrial...
