Instead of a sampling issue, clustering can also be an experimental design issue, when clusters of units, rather than units, are assigned to a treatment. In the view developed in this

WebThis method is known as dyadic clustering, denoted here ‘DC’, and we let DCdenote the covariance matrix under the Fafchamps and Gubert (2007) assumption. Fafchamps and Gubert (2007) propose a simple way to estimate the elements in DC: Covd(˘ ij;˘ kl) = r ijr kl, where r ijand r klare the residuals of the corresponding relations.
