Valid models require defined levels
ion. So now, let us try to describe abstraction. Here are some dictionary definitions: “abstract adj. 1. Considered apart from concrete existence . . . 4. Thought of or stated without reference to a specific instance.” “abstraction n. The process of extracting the underlying essence, removing dependence on real world objects.” Abstraction allows designers and modelers to describe a problem at a...
متن کاملTranspulmonary thermodilution assessments: precise measurements require a precise procedure
When incorporating the values of a hemodynamic parameter into the care of patients, the precision of the measurement method should always be considered. A prospective analysis in the previous issue of Critical Care showed that the precision of transpulmonary thermodilution (TPTD) allows for reliable mean values if a standardised procedure is used. The present finding has a physiological basis, ...
متن کاملWith Reference to Reference Genes: A Systematic Review of Endogenous Controls in Gene Expression Studies
The choice of reference genes that are stably expressed amongst treatment groups is a crucial step in real-time quantitative PCR gene expression studies. Recent guidelines have specified that a minimum of two validated reference genes should be used for normalisation. However, a quantitative review of the literature showed that the average number of reference genes used across all studies was 1...
متن کاملTrying to be precise about vagueness.
A previous investigation by Lambert et al., which used computer simulation to examine the influence of choice of prior distribution on inferences from Bayesian random effects meta-analysis, is critically examined from a number of viewpoints. The practical example used is shown to be problematic. The various prior distributions are shown to be unreasonable in terms of what they imply about the j...
