Estimand An estimand is that which is to be estimated in a statistical analysis. The term has recently seen increased use in the clinical trials community in order to more clearly distinguish the target of inference from different possible estimators and estimates. == Overview ==
An estimand is closely linked to the purpose or objective of an analysis. It describes what is to be estimated based on the question of interest.〔 This is in contrast to an estimator, which defines the specific rule according to which the estimand is to be estimated. While the estimand will often be free of the specific assumptions e.g. regarding missing data, such assumption will typically have to be made when defining the specific estimator. For this reason, it is logical to conduct sensitivity analyses using different estimators for the same estimand, in order to test the robustness of inference to different assumptions〔
