The multilevel medical condition file for each respondent allowed for the estimation of this unobservable heterogeneity.
For the evaluation of the effectiveness of the intervention we compared each of the experimental conditions with the control condition, using multilevel analysis to allow for the clustering of observations within schools and within classes, using ML-win version 2.02 [ 24].
To test the differences between the conditions, mixed multilevel regression analyses will be used with a hierarchical backward elimination method.
We analysed the association of patient characteristics with the number of chronic conditions by multilevel mixed-effects linear regression allowing for random effects at the study centre and GP practice-within-study centre level.
The testlet model accounting for the item clustering effect was slightly conservative in terms of type I error rate across all conditions, and the power was even lower than the multilevel testlet model under certain conditions.
We use the term "multilevel modeling" hereafter.
The testlet model cannot estimate DIF parameter as accurately as the multilevel testlet model under most conditions, but was slightly more efficient than the multilevel testlet model.
The potential to extend the municipal "horizon of attention" depends on multilevel actor constellations and framework conditions of which some are discussed in the following.
To provide a solution to images captured under extremely nonuniform lighting conditions, methods like multilevel windowed inverse sigmoid (MWIS) [11] and space-variant luminance map (SVLM) [12] were proposed in 2006 and 2010, respectively.
Therefore we are presently studying the central carbon metabolism under such dynamic conditions by a multilevel approach, where transcripts, enzyme activities, metabolites and fluxes will be integrated.
Community members created a multilevel governance system to address conditions that were negatively affecting their health: they constructed a potable water system, houses, and latrines; developed a food production system; and created an educational model that was popular with teachers and community health agents and that promoted health and rehabilitation (Guarjila, El Salvador).
