This function aims at quickly building a quadratic voting questionnaire
Details
The questionnaire comes with limitation as it can process not more than 5 groups of maximum 5 indicators. Each indicators is associated to different levels that will be then assessed through conjoint analysis for the weighting stage
After quadratic voting, it is expected that the facilitation of the result interpretation should allow to reduce the numbers of indicators to a maximum of 12 indicators
Examples
indicator <- system.file("data-demo/indicator_criteria.xlsx",
package = "VulnerabilityScoreCalibration")
#quadratic_prepare(indicator)
