  1. Expressed ambiguous and unambiguous 10 base pair tags for two LongSAGE libraries were distinguished based on the number of 17 base pair sequences that give rise to the same tag. The tags in each of these two groups were binned according to the number of estimated mixture components. The Chi-square statistic was used to test the null hypothesis that these two groups are equivalent.
