The structural uncertainty represents the uncertainty inherent in the DNDC model and is set using independent validation data (directly measured daily methane fluxes on benchmark sites) available at the time of methodology publication.

Not exact matches

Any results that are reported to constitute a blinded, independent validation of a statistical model (or mathematical classifier or predictor) must be accompanied by a detailed explanation that includes: 1) specification of the exact «locked down» form of the model, including all data processing steps, algorithm for calculating the model output, and any cutpoints that might be applied to the model output for final classification, 2) date on which the model or predictor was fully locked down in exactly the form described, 3) name of the individual (s) who maintained the blinded data and oversaw the evaluation (e.g., honest broker), 4) statement of assurance that no modifications, additions, or exclusion were made to the validation data set from the point at which the model was locked down and that neither the validation data nor any subset of it had ever been used to assess or refine the model being tested

The team then selected a subset of data for developing a panel for differentiating between pancreatic cancer and healthy pancreas tissue and thereafter applied this «Pancreatic Cancer Predictor» to the remaining datasets for independent validation to confirm the accuracy of the markers.

Well, it seems that the ACT report card and the other data represent a validation of educator performance independent of the dreaded and vilified TAKS and STAAR assessments, including the significant disconnect with the graduation statistics.

[Response: The satellite altimeter data point is shown in our Vermeer & Rahmstorf 2009 paper as an independent validation point that was not used for calibration, and it fits the relationship perfectly.

Parameters are determined with data independent from that to be used for the validation test.

Such reliance is data intensive and hence independent validation of terrestrial system models is problematical.

However, when a validation was performed on a similar analysis for which the regression model was calibrated with a subset of the data, and the remaining data were used for validation, it became apparent that models based on the factors that McKitrick & Michaels used had no skill (i.e. were not able to reproduce the independent data).

Oreskes (1998) argues for model evaluation (not validation), whereby model quality can be evaluated on the basis of the underlying scientific principles, quantity and quality of input parameters, the ability of a model to reproduce independent empirical data.

Fully independent reconstructions will allow mutual validation during their overlapping time intervals and spectral ranges and will help test methods for fusing high - and low - resolution paleoclimate data.

But if you are concerned about truth, science, reconciliation of data, independent validation of results, etc. etc. do it where you can make a difference.

Furthermore, since the data are historical, the analysis here is essentially that of a hindcast, and it is debatable to what extent the data can be considered to provide truly independent validation of the models.

I agree there are other possibilities, but if we believe that adjustments are relatively unimportant (Nick's work seems pretty persuasive here as independent validation of BESTs work), to me the most plausible candidate is spatial sampling effects (note this is really tempo - spatial, since there could be differences in the amount of annual data used at the same site between the series).

But according to a so - called «validation study» conducted by an unbiased independent researcher, a Dr. Edward Jo from the California State Polytechnic University, the data reported by the three wearable gadgets in question is not just in average off by 20 beats per minute compared to a separate, much more precise heart rate supervisor, but also «sporadic», «ambiguous», and «all over the place.»
