This region of validity depends on uncertainties in the parameters.
No co-factors were included, and due to the reliance on historical records, the data validity contains some uncertainties (Grade 2).
There are four categories of uncertainty that can affect the validity of a trust: conceptual uncertainty, evidential uncertainty, ascertainability and administrative unworkability.
Finally, three models including deterministic optimal scheduling, optimal scheduling considering the randomness of intermittent generation, and optimal scheduling that considers double uncertainty are compared to verify the validity of the double-uncertainty optimization model and the algorithm.
To further increase reliability, and to ensure the clinical validity of the diagnoses, uncertainties were regularly discussed with senior psychiatrists during sessions of group supervision.
Gaps concerning internal validity are related to uncertainties of potential bias risk due to inadequate randomisation, concealment of the random allocation, as well as blinding/masking.
When few data or information are available, the validity of studies performing uncertainty analysis or robust design optimisation (i.e., parameter optimisation under uncertainty) with a probabilistic approach is questionable.
Validation procedures for the period between 2001 and 2002 were conducted to ensure the validity of the selected uncertainty parameters through the calibration process.
While the seawater properties library routines are freely distributed, it is requested that users of this library please cite the following two journal articles which comprehensively present how correlations in the library were developed, the original data sources, the validity ranges, and the uncertainty in each property function.
Each of these broad approaches addresses validity and characterizes the uncertainty of results from a single study and extends to improved characterization of epidemiologic results in weight-of-evidence assessments.
The term has been used to refer to methods for establishing both internal and external validity by decreasing the uncertainty of a single measurement by making multiple observations [ 4].
