"WebThe proposed modi ed JEL (mJEL) procedure is shown to be asymptotically valid regardless of the presence of dyadic clustering. In prac- tice, dyadic clustered data are often incomplete or contain missing values. We extend our modi ed JEL procedure to cover the practically relevant case of incomplete data under the missing at random assumption. " - Dyadic clustering

WebAbstract. Bipartite graphs can be used to model a wide variety of dyadic information such as user-rating, document-term, and gene-disorder pairs. Biclustering is an extension of clustering to the underlying bipartite graph induced from this kind of data. In this paper, we leverage optimal transport (OT) which has gained momentum in the machine ... WebAs a result, our approach complements the existing methods based on dyadic clustering, sim-ilar to how inference with spatial data (e.g.,Conley(1999) andJenish and Prucha(2009))5 complements one-way clustering inference. Which approach to pursue using dyadic data depends on the researchers’ applications and how they t such assumptions.
