Comparison of LSA values: fastLSA and Original LSA. A comparison of calculated LSA statistics between FASTLSA and Original LSA implemented by [6] and calculated on the CDC dataset. There is an almost one-to-one correspondence between calculated values. The one outlying value was likely due to the transform that the original LSA applies, causing a disagreement between positive and negative values. For a single value fastLSA picked the negative value (-0.4) and original LSA picked positive (0.4).
