A negative binomial model fits the data. Observed mean-variance relationships fit as compared to the negative binomial (NB) model. Dots are observed values derived from 260 ST count distributions with a separately fitted dispersion parameter. The red line is the relationship predicted by the NB model with fixed d (0.125). Data derived from twenty ST-only samples described in the ST-only data sets
