Résumé

We derive necessary and sufficient conditions for a sum of i.i.d. random variables $\sum_{i = 1}^{n} X_{i} / b_{n}$ - where $\frac{b_{n}}{n} ↓ 0$ , but $\frac{b_{n}}{\sqrt{n}} ↑ \infty$ - to satisfy a moderate deviations principle. Moreover we show that this equivalence is a typical moderate deviations phenomenon. It is not true in a large deviations regime.
