Abstract: The description of the abundance and clustering of haloes for non-Gaussian initial conditions has recently received renewed interest,motivated by the forthcoming large galaxy and cluster surveys, which can potentially yield constraints of the order of unity on the non-Gaussianity parameter f(NL). We present tests on N-body simulations of analytical formulae describing the halo abundance and clustering for non-Gaussian initial conditions. We calibrate the analytic non-Gaussian mass function of Ma
