Asymptotics for the L p -deviation of the variance estimator under diffusion
ESAIM: Probability and Statistics, Tome 8 (2004), pp. 132-149.

We consider a diffusion process X t smoothed with (small) sampling parameter ε. As in Berzin, León and Ortega (2001), we consider a kernel estimate α ^ ε with window h(ε) of a function α of its variance. In order to exhibit global tests of hypothesis, we derive here central limit theorems for the L p deviations such as

1 hh ε p 2 α ^ ε -α p p -𝔼α ^ ε -α p p .
