The maximum variance of this distribution is 0.25, which occurs when the true parameter is p = 0.5. In practical applications, where the true parameter p is unknown, the maximum variance is often employed for sample size assessments. If a reasonable estimate for p is known the quantity () may be used in place of 0.25.
Illustration of the Kolmogorov–Smirnov statistic. The red line is a model CDF, the blue line is an empirical CDF, and the black arrow is the KS statistic.. In statistics, the Kolmogorov–Smirnov test (also K–S test or KS test) is a nonparametric test of the equality of continuous (or discontinuous, see Section 2.2), one-dimensional probability distributions.
In other words, S(X) is minimal sufficient if and only if [11] S(X) is sufficient, and; if T(X) is sufficient, then there exists a function f such that S(X) = f(T(X)). Intuitively, a minimal sufficient statistic most efficiently captures all possible information about the parameter θ.

Simms, alongside Charlie Mason, later wrote that Ashland was the "Second-Best New Character" of 2021 in American soap operas, calling him the "Locke Ness Monster", but wanted the soap to show "just how bad Richard Burgi's Big Bad is instead of merely telling us over and over again that he's powerful and scary".
