Both Chandler and Modelski used diverse sets of variables to determine their final city population counts.
Both sets of variables elicited similar prediction quality.
Since the 1980's, other groups have developed alternative indexes of social health using different sets of variables.
For data processing and analysis, a custom software (Matlab; MathWorks, Natick, MA) was used to compute two sets of variables.
First, we define a canonical problem form called graph form, in which we have two sets of variables and related by a linear operator, such that the objective function is separable across these two sets of variables.
The ensuing recent sets of variables studied aimed at deepening the understanding of the operational limits.
Using this algorithm, the correct sets of variables were found for two artificial problems.
These matrices could have been obtained using different sets of variables and dissimilarity functions.
These matrices have been generated using different sets of variables and dissimilarity functions.
These matrices can be obtained using different sets of variables and dissimilarity functions.
The key notion is that of recoveries, which are sets of variables whose forgetting enables restoring consistency.
