Description Readers' comments

A calibration procedure is generally performed in order to correctly translate the personal traits observed through a psychometric test into numerical values. The calibration process ensures the objectivity of the measure instruments. Psychological measures are usually of indirect type, they are obtained as a result of a statistical inference process. Statistical calibration makes use of particular models, based on the inversion of the previous mentioned indirect measures. The Rasch model can be considered one of this model.

Keywords: statistical calibration, intelligence test, Rasch analysis.
