Distinguishability between the pure transmission modes based on selected statistics: the joint probability distribution of the five variants of a trait in the population, fjoint,x, the level of cultural diversity, dxs, and the average time a variant stays the most common variant, tmaxx. Shown are the values of the area of overlap Oxy between the probability distributions of the statistic for pairs of modes, under parameter constellation N=50, μ=0.1, pw=1. Values in italics indicate distinguishability based on threshold O¯=0.2.
