Overall, the effects of heterogeneity
are far less definitive with fixed effects than with cross-section analysis.
Our hypotheses indicate that firm complexity and managerial power affect board heterogeneity
(Fama and Jensen, 1983; Yermack, 1996; Klein, 1998).
We are concerned, however, that the reporting of HER2 genetic heterogeneity
(GH) may produce greater inconsistency of HER2 testing and lead to confusion about a patient's clinical HER2 status.
Copeland's approach to constructing the software component of the cost-of-living price index explicitly accounts for consumer heterogeneity
Based on scientific notions, like stochastic heterogeneity
and structure-sensitivity, which are at the very heart of materials science and stereology, the paper demonstrates biases in obtained information to be generally inevitable when derived from such sub-representative designs.
They present the basic model, then describe modeling unobserved heterogeneity
and covariate information, using alternate approaches, incorporating covariate information and unobserved heterogeneity
, working with modeling tools, estimating odds ratios using the profile likelihood, and quantifying heterogeneity
in an MAIPD.
First, there was a considerable degree of clinical heterogeneity
between studies in terms of type of cancer, mode and intensity of exercise, and timing of the exercise intervention.
These data allowed me to determine the effects of geographic heterogeneity
at macro and micro-spatial scales on arboreal size and distribution.
Dispersion of QT interval was studied as an index of repolarization heterogeneity
in hypertensive men.
, Performance, Global Teams, Global Dispersion
Despite the acknowledgment of the tumor cellheterogeneity, little evidence was shown about complexity and dynamics of this heterogeneity
in vivo,mainly because of lacking flexible genetic tools which allow sophisticated analysis in primary tumors.
recently ascribed the origin of the slow mode to heterogeneity
in the polymer solution [19, 20], To elaborate, when the polymer concentration (C) is lower than the entanglement concentration ([C.
