Choosing the Allometric Exponent in Covariate Model Building
Clinical Pharmacokinetics, 2018Allometric scaling is often used to describe the covariate model linking total body weight (WT) to clearance (CL); however, there is no consensus on how to select its value.The aims of this study were to assess the influence of between-subject variability (BSV) and study design on (1) the power to correctly select the exponent from a priori choices ...

Allometric Weight–Length Regression Model
Journal of the Fisheries Research Board of Canada, 1969Two methods of fitting the allometric weight–length relationship are described, one involving the common logarithmic transformation of variables in a multiplicative model and the other assuming an additive nonlinear model and general nonlinear estimation procedures.

An Allometric Tridimensional Model of Self-Thinning for a Gregarious Tunicate
Ecology, 2001A tridimensional allometric model of self-thinning was tested in a tunicate population of Pyura praeputialis in the Antofagasta Bay, northern Chile. The theory tested follows the bidimensional allometric theory of Osawa and Allen for the self-thinning rule proposed for plants, except that in addition to mean individual mass we included three new ...

A Mathematical Model of Stroma-Supported Allometric Tumor Growth
Bulletin of Mathematical BiologyMounting empirical research suggests that the stroma, or interface between healthy and cancerous tissue, is a critical determinate of cancer invasion. At the same time, a cancer cell's location and potential to proliferate can influence its sensitivity to cancer treatments.

A Generalized Allometric Model for Determining Length‐Weight Relationship
Biometrical Journal, 1997AbstractWell‐known allometric model is critically reviewed for determining the length‐weight relationship. Procedure to be followed for applying this model under the assumption of multiplicative as well as additive error is discussed. The possibility of autocorrelations in error term is explored.

Abiotic forcing in allometric trophic network models
2022Current ecological research and ecosystem management call for improved understanding of the abiotic drivers of community dynamics, including temperature effects on species interactions and biomass accumulation. Allometric trophic network (ATN) models provide an attractive framework to study consumer-resource interactions from ...

An allometric model for predicting blood ethanol elimination in mammals
Biochemical Pharmacology, 1999The relationship of ethanol elimination kinetics in mammals was estimated using the allometric principle. The hypothesis of relationships between parameters obtained from the compartment model with Michaelis-Menten elimination kinetics and body weight can lead to common equations of blood ethanol elimination in mammals. The maximum elimination velocity

A General Model for the Origin of Allometric Scaling Laws in Biology
Science, 1997Allometric scaling relations, including the 3/4 power law for metabolic rates, are characteristic of all organisms and are here derived from a general model that describes how essential materials are transported through space-filling fractal networks of branching tubes.

Allometric Extension for Multivariate Regression Models [PDF]
, 2006 In multivariate regression, interest lies on how the response vector depends on a set of covariates. A multivariate regression model is proposed where the covariates explain variation in the response only in the direction of the first principal component axis.
