To determine if self-reported balance symptoms can be used as a proxy for measures of the center of pressure (COP) to identify balance deficits in a group of concussed adolescents.
The location at baseline (for eight locations from the most to least secure) predicted harm to others (AUC = 0.812, 95% confidence interval 0.677 to 0.948, p < 0.001) as expected, since we have previously shown that location is a proxy for measures of risk [ 32] and recovery [ 23, 24].
Then in 2011 I heard about a finger-tapping test being used as a proxy for measuring the effects of medication in Parkinson's.
where α, γ, δ, β = s ε are positive parameters, τ is the delay in the production process, γ can be thought of as a proxy for measuring returns to scale of the production function, δ reflects a strength of a 'negative effect' caused by increasing concentration of capital and is determined by a damaging degree of natural environment or energy resources.
(1.2) Here (alpha,gamma,delta), and β are positive parameters, δ reflects the strength of a 'negative effect' caused by increasing concentration of capital, γ is a proxy for measuring returns to scale of the production function and (beta=sc), where c is a positive constant.
Since researchers have extensively used calls for services (CFS) to police as a proxy for measuring crime (e.g., Sherman et al. 1989; Sherman 1995; Lum 2003; Weisburd et al. 2006), we wanted to see if studies using crime incident data systematically displayed more or less concentration than studies using CFS data.
While Montgomery et al. (2000) noted that the WI may not be efficient as a proxy for measuring income distribution [25], Filmer and Pritchett (2001) concluded that WI had advantage of allowing better analysis of education differentials by economic status than did an expenditure index [39].
Analysts could use the Caixin index as a proxy for measuring the progress in reform.
One experiment we ran earlier today asked people at the end of a story a very simple question: "Did you love this story?" Instead of having a proxy for measuring impact, why don't we just ask them?
Over the years, getting on AR's rich list has become a point of pride and vanity for top managers -- as the list is a proxy for measuring a managers success.
However test performance can be assessed indirectly by employing a gradient of exposure or by using active TB as a proxy for measuring sensitivity to LTBI [8], [9].
