The word . is derived from Greek words meaning “without protection.” Although the hypersensitive condition induced by repeatedly injecting an antigen may appear to reflect some deficiency in the animal’s humoral protective system, we now know tha

Introduction,wnian diffusions. In first place one considers the situation where the observed Brownian trajectory is smoothed by a convolution filter, the filter tends to the Dirac delta distribution when some specific parameter tends to zero. The second situation corresponds where the process is observed in a me

The attention will be focused on pathwise integrals. The existence of the integral as the limit in probability of the

Moreover, for a general functional variation of the fBm, see (.), page 40, including the absolute .-power variation, the result remains true. This allows us to propose several estimators o

Simulation Algorithms and Simulation Studies,imulation of processes driven by a fBm. Our approach is based on Durbin-Levinson’s algorithm. Since the process formed by the first order increments of a fBm is a stationary Gaussian one, we first simulate the increments of the process and then, by a simple “integration”, we obtain a trajectory of t

Indeed, in that section we explain that in the case where . ≡ 0, the solution of the SDE is .(.) = .(..(.)) where . is a solution of an ODE and thus we assert that proving results enunciated in Remarks . and . is equivalent to prove them for the fBm. These lemmas give in an explicit manner h
