The variances of the two error terms are estimated among other parameters from the data.

Mean longitudinal prevalence of diarrhea was estimated among participants of all ages.
HCV prevalence is very high (estimated among adults at 10 and 20% in urban and rural areas respectively) [14].
Still, fluctuations among replicate experiments are large (the estimated among experiment variance is 3.012 which is larger than the estimated variance among selection lineages).
Median follow-up times were estimated among surviving patients.
