Detection of real periodicity in the terrestrial impact Crater record: quantity and quality requirements.

LYYTINEN J., JETSU L., KAJATKARI P. and PORCEDDU S.

Abstract (from CDS):

To determine the quantity and quality requirements for the terrestrial impact crater data which would allow reliable detection of real periodicity. Artificial impact crater data samples of different size and accuracy are simulated. Erosion is considered, as well as the effect of the unknown ratio between periodic and aperiodic impacts. The probabilities for detecting real and false periodicities are solved with the Rayleigh test from these simulated data. Reliable detection of real periodicity is currently impossible - unless all impacts on Earth have been periodic.
