Thus, a multivariate model is estimated that also adjusts for differences between MRI and non-MRI practices in practice characteristics ("Practice j,r,t ") and county-level practice area characteristics ("Area r,t ") that remain after PS matching.
However, the potential for technologies to foster learning self-regulation processes in students and the deployment of learning strategies requires a suitable technopedagogic design of tasks and activities, not just depending on ICT characteristics (Area, 2007).
We developed a model based on stochastic decision trees (SDTs) to integrate farm type and field characteristics (area, distance to farmstead, waterlogging, and current crop) in the spatio-temporal allocation process without prior expert knowledge, and we compared the model to a reference model based on first-order Markov chains or transition matrices.
Many of these studies examined the relationship between body size and three island physical characteristics: area, age, and distance from mainland source.
aReceiver operator characteristics area under the curve (ROC AUC) for the renal angina index.
The screener had very good test characteristics (area under the receiver operating characteristic curve = 0.89).
The discriminating operating characteristics area of the selected items was 0.777 955% CI 0.755 to 0.797; P < 0.001).
The following indicators of criterion validity were calculated: positive predictive value, negative predictive value, sensitivity, specificity, overall accuracy and receiver operating characteristics (area under the curve, AUC) [ 35].
Data on demographic characteristics, area (rural vs. urban), household economic status, whether the adolescent was registered at school or not at the time of the survey, low physical activity, and perceived stress were collected using interviewer-administrated questionnaires.
Given the superimposable relapse rate of patients falling into the very low, low, and intermediate risk groups, all three risk categories were grouped together into a unique lower-risk group (LRG), whereas the high-risk group (HRG) corresponds to the original NIH category (receiver operating characteristics area: 82.6%).
These results were not significantly different after exclusion of subjects treated with warfarin or low molecular weight heparin (LMWH) (discriminating operating characteristics area of 0.783 (95% CI 0.746 to 0.820; P < 0.001)) and in the subgroup of subjects fully recovered or with moderate disability at six months, that is, GOS 4 to 5 (0.716, 95% CI 0.645 to 0.786; P < 0.001).
