CD Genomics is able to use directed acyclic graph analysis services for medical and clinical research to help customers identify confounders and sources of bias.
A directed acyclic graph is a directed graph with no loops in the graph. It consists of nodes and connections between nodes with one-way arrows. Because directed acyclic graphs can describe preference or dependency relationships in a natural way, they are widely used in bioinformatics analysis. A directed acyclic graph is a theory-driven method for screening independent variables, which constructs causal networks based on theoretical causal relationships. Arrows are used to represent causal relationships, with arrows emitting objects as causes and arrows pointing to outcomes.

A directed acyclic graph illustrates a specific set of assumptions that may be incorrect and can help provide an opportunity for customers to decide which potential impacts to take into account. Our researchers rely on the visual presentation of a directed acyclic graph to help customers infer which variables need to be controlled for in the statistical analysis and which variables may cause additional bias when controlled for in the analysis.
