  The statistics of tunneling current in a fractional quantum Hall sample with
an antidot is studied in the chiral Luttinger liquid picture of edge states. A
comparison between Fano factor and skewness is proposed in order to clearly
distinguish the charge of the carriers in both the thermal and the shot limit.
In addition, we address effects on current moments of non-universal exponents
in single-quasiparticle propagators. Positive correlations, result of
propagators behaviour, are obtained in the shot noise limit of the Fano factor,
and possible experimental consequences are outlined.
