Kurtosis, in particular, is calculated from the diffusion and the Burnett coefficients, which are obtained analytically. A characteristic time scale delimiting the onset of the Markovian regime for the master equation is established. Some explicit examples are discussed.19 pages, 6 Figures. v2: Grammatical corrections, new referencesChaotic Dynamicstext
