Exporting .CHO File


You may export a *.CHO file containing the items displayed in each set and the respondent answers.  This is a text-only file that may be used with our CBC/HB or Latent Class v2.5 software for score estimation outside of the MaxDiff system.


When you export a *.CHO file for your MaxDiff exercise, additional files are also created:


ExerciseName.ATT                (Attribute file)

ExerciseName.EFF                (Effects file)

ExerciseName.VAL                (Values file)

ExerciseName.MTRX                (Default Prior Covariance Matrix)


These files are required by the Latent Class v2.5 system (except the .MTRX file, which is used only by CBC/HB).
