Figure 1.
The workflow of the step-wise analysis plans is shown. The framework illustrates how we explored different ways of evaluating the diagnostic performance beyond the one-locus model (using parametric linear model). We proposed to use Random Forest classification algorithm to identify the optimal subset of predictors in the context of multi-locus effects. It also includes how we investigated the relationships among the genes that harbor different tissue-specific asthma-associated DNAm signatures.
