The phrase "a second set of estimates" is correct and usable in written English.
You can use it when referring to an additional group of estimates that have been created or calculated after the first set.
Example: "After reviewing the initial projections, we decided to create a second set of estimates to ensure accuracy."
Alternatives: "an additional set of estimates" or "a follow-up set of estimates."
A second set of exposure estimates was created for the full cohort using estimates of PM2.5 derived from satellite remote sensing observations during the period 2001 2006 [ van Donkelaar et al. 2010; for additional descriptions of the satellite data retrievals, see Supplemental Material (http://dx.doi.org/10.1289/ehp.1104049)].
In the case of the parametric ODE model of the JAK2-STAT5 signalling pathway, we showed that in addition to the parameter estimates obtained from the original dataset, there is a second set of plausible estimates which (had stochastic effects provided us with a slightly different dataset) we may well have concluded were the 'correct' values.
When we compared the allele frequencies calculated from the average of only three microarray replicates from one pool with that calculated from the average of a second set of three estimates for the same pool, the correlation between measures was r = 0.996.
A second set of GLMs estimated the relationships of single destination variables with non-transport sitting and motorised transport, adjusting for the above sociodemographic covariates and environmental covariates.
Although we find that the parameter estimates inferred from the original dataset are relatively robust to data uncertainty, we also identify a distinct second set of estimates.
In the third phase, we used a second set of simulations to estimate sample size and sampling frequency required to have a reasonable chance of detecting a minimum trend in vegetation cover for a specified time period and level of statistical confidence.
Consequently, we initiated a second set of trials to estimate the effect of humidity at the temperature where recorded clinging forces were maximal for both species (12°C).
While some subgroup analyses based on the second set of estimates seem to suggest a possible association, all of these are heavily dependent on the contribution of one specific relative risk estimate from one study with known weaknesses [ 11].
The second set of estimates focuses on WIA participants who were receiving UI benefits at the time they entered WIA.
