  We calculate the first four moments of baryon number, electric charge and
strangeness fluctuations within the hadron resonance gas model. Different
moments and their ratios as well as skewness and kurtosis are evaluated on the
phenomenologically determined freeze-out curve in the temperature, baryon
chemical potential plane. The model results and its predictions as well as
relations between different moments are compared with the first data on net
proton fluctuations in Au-Au collisions obtained at RHIC by the STAR
Collaboration. We find good agreement between the model calculations and
experimental results. We also point out that higher order moments should be
more sensitive to critical behavior and will also distinguish hadron resonance
gas model calculations from results obtained from lattice QCD.
