Therefore, heuristics have been designed to select reasonably good variable orderings.
With correlation coefficients of this magnitude, self-reported birth weight can be used as a reasonably reliable variable in epidemiological analyses, although the strength of any association may be underestimated due to regression dilution bias [ 23].
We did have reasonably satisfactory variables available in our data set for home-based care practices and food availability, but the availability of health services and healthy environment variables was less satisfactory.
"I think they will be proved right that some of those early African fossils can reasonably join a variable Homo erectus species," said Chris Stringer, head of human origins at the Natural History Museum in London.
"I think they will be proved right that some of those early African fossils can reasonably join a variable Homo erectus species," paleoanthropologist Chris Stringer at the Natural History Museum in London, who did not take part in this study, told LiveScience.
We picked 8 variables including AGE, RACE, SMOKE, PTL, HT, UI, FTV, BWT from the dataset, and reasonably modified several variables to create a new dataset as follows.
The effect estimates were materially unchanged with additional adjustment (Table 2, model 2), suggesting that our base adjustment variables reasonably controlled for SES or that bias from SES was minimal, although it cannot prove that we have not omitted some critical unmeasured (U) variable.
In accordance with a recent publication from the Duisburg birth cohort (Rennert et al. 2012) and to keep the list of exposure variables reasonably short, we excluded the non- ortho- and the mono- ortho-substituted PCBs, the unweighted Σ6-PCBs, and the NATO/CCMS-TEQ weighted dioxiNATO/CCMS-TEQ weightederation.
According to Spearman's correlation, the temperature variables and the duration variables had reasonably low correlation (0.35 in summer and −0.29 in winters), and the variance inflation factor (VIF) indicated no collinearity problems.
Sensitivity analyses showed the results to be reasonably insensitive to variability in key assumptions and variables.
