Run statistics Distribution of number of deletion events r composing each run when the proportion of sequence deleted is 0.5 (top left) and 0.9 (top right). Distribution of run length, reflecting a mixture of negative binomial distributions, for two values of the parameter of the underlying geometric distribution (bottom left). Identical results for simulation interval of 100,000 or 300,000 genes (bottom right).
