Network-based diffusion analysis
open-in-new
<p>Network-based diffusion analysis (NBDA) is a statistical tool to detect and quantify social transmission of information or a behaviour in social networks (<a href="/facts/Social_network_analysis/CsJIFjVw">SNA</a>, etc.). NBDA assumes that social transmission of a behavior follows the social network of associations or interactions among individuals, since individuals who spend a lot of time together, or who interact more have more opportunity to learn from each other. Therefore, NBDA infers social transmission if the spread of a novel behavior follows the social network of a <a href="/facts/Population/ArxshNuB">population</a>. NBDA thus allows the study of <a href="/facts/Social_learning_theory/IcbScxFv">social learning</a> to be linked to <a href="/facts/Ethology/dM3CpysA">animal behavior</a> research that uses social network analysis. NBDA was introduced by Franz & Nunn and further developed by Hoppitt, Boogert, & Laland. </p>
