For the first example, consider a small website that is a platform for content on personal finance. How willing your users are to engage with personal finance content depends on whether or not it’s the weekend. For this reason we don’t report uncertainty measures or statistical significance in the results of the simulation.

Unlike experimentation in some other areas, LSOS experiments present a surprising challenge to statisticians — even though we operate in the realm of “big data”, the statistical uncertainty in our experiments can be substantial. We must therefore maintain statistical rigor in quantifying experimental uncertainty.

The result is that experimenters can’t afford to be sloppy about quantifying uncertainty. These typically result in smaller estimation uncertainty and tighter interval estimates. We previously went into some detail as to why observations in an LSOS have particularly high coefficient of variation (CV).
