Key: DCS_Weight_DefaultMaxIteration=
Syntax
<add key="DCS_Weight_DefaultMaxIteration" value="[NUMBER]"/>
[NUMBER]: Positive integer number
Purpose
Used for the weight calculation logic in the data cache module.
The default maximum iterations is just the default value that is given to users when using the weight wizard. It is possible for users to change it subsequently via the wizard.
The way that weights are being calculated is through a number of iterations where the system closes in on the appropriate weight of each respondent in the data cache. The default number of iterations is e.g. set to 50 but can be increased up to a pre-defined number set in the configuration file for the system (in the key DCS_Weight_MaximumMaxIteration). In our experience the number of iterations needed for convergence is ranged from 2 to 30 and depends on how heavily unbalanced the sample was initially. Even though the default number of iterations is set to 50, the iterations will terminate as soon as convergence is achieved.
Proposed value is "50".
Example of key
<add key="DCS_Weight_DefaultMaxIteration" value="50"/>
