Even though the concordance of the analyses based on the reduced subsets suggest that the results are robust, the possibility of unknown confounding cannot be excluded.
Although further separation of drinking limits would make the analysis and interpretation of the study less robust, the possibility of residual confounding within narrower age bands needs to be considered.
Regarding the issue of stationarity, and even when the technique used is considered to be robust to different possibilities (existence of cointegration relationships or not), we have tested this property on the residuals.
To avoid transition problems between versions, amendments should be made with care to provide robust re-coding possibilities.
A competitive distribution of auctions (Peters 1997) is robust to the possibility of a seller's deviation to any arbitrary mechanisms, let alone direct mechanisms because the sufficient condition for the robustness is embedded in its notion of equilibrium.
We study what kind of equilibria of which mechanisms are ex post renegotiation-proof (EPRP), i.e., robust against the possibility of ex post renegotiation under a variety of renegotiation procedures, and which social choice functions are EPRP implementable.
The observed synteny of chromatin communities was also robust against the possibility of artifacts due to genomic rearrangements in human cancer cell lines.
This conclusion is also robust to the possibility of stronger selection in mtDNA than in nuclear DNA, as our method compares the shortest possible extinction times for all corresponding selection coefficients (stronger selection on mtDNA than assumed will lead to even longer extinction times).
Saving time is one important factor, but in addition, automation limits human error and extends possibilities for robust, objective and reproducible analysis.
From a local to regional resource monitoring perspective [16], earth observation provides additional useful spatial and temporal resolution (Figure 10), while regions with frequent cloud cover reduce the possibilities for robust continent-wide monitoring of plant productivity in Africa.
