In statistical inference problems, we wish to obtain lower bounds on the minimax risk, that is to bound the performance of any possible estimator. A standard technique to do this involves the use of Fano’s inequality. However, recent work in an information-theoretic setting has shown that an argument based on binary hypothesis testing gives tighter converse results (error lower bounds) than Fan...

FAO has recently started the “Capacity and Institution Building Portal” to provide structured access to information on FAO’s capacity and institution building services and learning resources. To ensure that the Portal can be searched by users and to enable interoperability...
