Design Choice Sets for DCE

Description

Design choice sets for DCEs.

Details

This dialog box uses the function rotation.design in package support.CEs to design choice sets for DCE with the rotation design method or mix-and-match method. For details on the results of this dialog box, refer to help for the function rotation.design.

GUI elements of this dialog box are as follows.

• Name for design: An R object name into which choice sets generated using this dialog box are stored. The default name ‘DCEdesign’ can be changed following R's rules for naming objects. If changed, you should take note of the new object name, which will be used later.

• Save to file: A check box used to save the resultant design to an external file in RDA format (.rda). If necessary, check this box.

• Design method: A method used to generate DCE choice sets. Select one from two radio buttons corresponding to ‘Rotation’ and ‘Mix-and-Match’. For the details on these methods, see help for function rotation.design.

• Number of alternatives per set (without opt-out): The number of alternatives per choice set (question), where an opt-out option is not counted as this number even if the opt-out option will be used in your survey.

• Number of blocks: The number of blocks into which the resultant DCE choice sets are divided.

• Quantitative: A check box showing that a quantitative attribute is set in the corresponding row.

• Attribute: An attribute variable name following R's rules for naming variables. Type names without skipping from the first row.

• Level 1 to Level 6: Level variable names corresponding to the attribute entered in the first column. These variable names must also follow R's rules for naming variables. Type names without skipping from the ‘Level 1’.

• Seed for random number generator (optional): An integer value used as a seed for generating random numbers. If reproducibility is needed, type an arbitrary value into this box.

• Reproduce choice sets designed with R < 3.6.0: A check box for reproducing DCE choice sets generated with R versions older than 3.6.0. If necessary, check this box.
