Equiprobable discrete models of site-specific substitution rates underestimate the extent of rate variability.
It is standard practice to model site-to-site variability of substitution rates by discretizing a continuous distribution into a small number, K, of equiprobable rate categories. We demonstrate that the variance of this discretized distribution has an upper bound determined solely by the choice of K...
