Comment on “Two statistics for evaluating parameter identifiability and error reduction” by John Doherty and Randall J. Hunt
Mary C. Hill
2010, Journal of Hydrology (380) 481-488
Doherty and Hunt (2009) present important ideas for first-order-second moment sensitivity analysis, but five issues are discussed in this comment. First, considering the composite-scaled sensitivity (CSS) jointly with parameter correlation coefficients (PCC) in a CSS/PCC analysis addresses the difficulties with CSS mentioned in the introduction. Second, their new parameter identifiability statistic...
Efficient estimators for adaptive stratified sequential sampling
M. Salehi, M. Moradi, Jennifer Brown, David R. Smith
2010, Journal of Statistical Computation and Simulation (80) 1163-1179
In stratified sampling, methods for the allocation of effort among strata usually rely on some measure of within-stratum variance. If we do not have enough information about these variances, adaptive allocation can be used. In adaptive allocation designs, surveys are conducted in two phases. Information from the first phase is...

Joel Moore, J. L. Macalady, Marjorie S. Schulz, Arthur F. White, Susan L. Brantley
2010, Soil Biology and Biochemistry (42) 21-31
Changes in the biomass and structure of soil microbial communities have the potential to impact ecosystems via interactions with plants and weathering minerals. Previous studies of forested long-term (1000s – 100,000s of years) chronosequences suggest that surface microbial communities change with soil age. However, significant gaps remain in our understanding...
