Standardizing procedures and terminology will provide important benefits, but standardizing variable measurements will be a major endeavor that will require both substantial time and resources to complete.
Because the 2006 2010 GPHL dataset reported both positive and negative submissions, there was opportunity to possibly mitigate the surveillance bias to some extent by incorporating a standardizing variable.
However, because our model counted the number of positive cases as the outcome variable, we wanted to use some form of the submissions data as the "weighted" standardizing variable on the right side of the regression model to normalize counties.
Because this distance is considered sensitive to the scale measure of the variables, standardized variables were therefore used.
It is essential to standardize variables in cases where the difference measure, such as the Euclidean distance, is sensitive to the changes in the magnitudes or scales of the input variables [18].
The centered and standardized variables are projected onto the space spanned by the two chosen components, inside a circle of radius 1.
Once standardized, variables were aggregated into a composite index Hs (scale 0 10) using multicriteria tools in geographic information systems (GIS) (Eastman 1999): where w1 – w n are weights assigned respectively to n variables/indicators, and SV1 – SV n are standardized values of these indicators for each town.
To define a precise meaning for input and output datapoints far beyond standardized variable types, semantic types are introduced.
Standardized variable fields [e.g., International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9) codes] are recorded for both ED visit and HA data [ 4- 6].
FFAS03 returns standardized variable ("Z") scores for comparisons between a query and a solved template structure sequence, with a score of 9.5 cited by the authors as being statistically significant.
