The idolatry of the surrogate

BMJ, 2011
Easier to measure surrogate outcomes are often used instead of patient important outcomes such as death, quality of life, or functional capacity when assessing treatments. John Yudkin, Kasia Lipska, and Victor Montori argue that our obsession with surrogates is damaging patient ...

SURROGATE-BASED HYPOTHESIS TEST WITHOUT SURROGATES

International Journal of Bifurcation and Chaos, 2004
Fourier surrogate data are artificially generated time series, that — based on a resampling scheme — share the linear properties with an observed time series. In this paper we study a statistical surrogate hypothesis test to detect deviations from a linear Gaussian process with respect to asymmetry in time (Q-statistic).

The Surrogate's Authority

Journal of Medicine and Philosophy, 2014
The authority of surrogates-often close family members-to make treatment decisions for previously capacitated patients is said to come from their knowledge of the patient, which they are to draw on as they exercise substituted judgment on the patient's behalf.

Surrogate Constraints

Operations Research, 1968
A surrogate constraint is an inequality implied by the constraints of an integer program, and designed to capture useful information that cannot be extracted from the parent constraints individually but is nevertheless a consequence of their conjunction.

Lung surrogates

Acta Anaesthesiologica Scandinavica, 1989
In the development and evaluation of mechanical ventilation on the basis of high‐frequency oscillation, appropriate surrogates of the lung are important, because they allow the measurement and control of various parameters which are not accessible in animal models.
