Well, it turns out that depending on what it cares to measure, an LSOS might not have enough data. The practical consequence of this is that we can’t afford to be sloppy about measuring statistical significance and confidence intervals. Being dimensionless, it is a simple measure of the variability of a (non-negative) random variable.
