Hunseckerized journalism has defined deviance down -- yet that's not an altogether bad thing.
But what's really happening is that the authority of the press to assume consensus, define deviance and set the terms for legitimate debate is weaker when people can connect horizontally around and about the news.
Indeed, to the extent that mental disorder is defined by deviance from societal norms, the very fact that anxiety about flying is so widespread has made the fear more socially acceptable, and thus less aberrant.
Figure 4 shows the 2D space formed by phonological skills and phonological representations, with the four quadrants defined by deviance thresholds set a priori at −1.5 SD below the control mean.
AIC, defined as deviance plus 2 times the number of predictors, measures the predictive power; a model is estimated to reduce out-of-sample prediction error if AIC decreases.
This, therefore, suggests that the specific profile of phonological deficits may differ, to some extent, between children with dyslexia and those with SLI. Figure 3 reproduces the 2D space of Bishop and Snowling (2004) and Fig. 1B, with the four quadrants defined by deviance thresholds set a priori at −1.5 SD below the control mean.
The deviance, defined as −2 times the log-likelihood, is a measure of goodness of fit; smaller deviance means better fit to data.
A general loss function based the likelihood function is the deviance defined as D y, θ) = -2log(L y| θ)), where L y| θ) denotes the likelihood function and log denotes the natural logarithm.
The tree construction process attempts to reduce the node deviance, defined as ∑ y − y ¯ 2, where y is the relative bias and y ¯ is the mean relative bias within a node.
Although classically gene gene interactions have been defined statistically as deviance from additive marginal effects, such as in the case of logistic regression model, this type of model is limiting with respect to statistical power.
