Minimax Lower bounds |
| Adityanand Guntuboyina |
| Abstract |
| Lower bounds on the minimax risk are useful in making impossibility statements about statistical problems and also in assessing the quality of decision rules. I shall present a general technique for obtaining such lower bounds that includes standard lower bound arguments like Le Cam's's method, Assouad's lemma and Fano's lemma as special cases. I shall also present some applications. |
