Design Choice Sets for BWS2

Description

Design choice sets for BWS2 with an orthogonal design.

Details

This dialog box designs choice sets (profiles) for BWS2 with an orthogonal design using the function oa.design in DoE.base.

GUI elements of this dialog box are as follows.

• Name for design: An R object name into which choice sets generated using the dialog box are stored. The default name ‘BWS2design’ 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.

• Name for attributes and levels: An object name into which attributes and their levels entered in the ‘Attributes and their levels’ table (explained later) are stored. The default name ‘BWS2attributs’ cannot be changed (A fixed variable is colored in green).

• Save to file: A check box for saving both the resultant design object and the items object to a single external file in RDA format (.rda). If necessary, check this box.

• Attributes and their levels: A specification (table) of attributes and their levels used to generate BWS2 choice sets.

• 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’.

• Randomize the order of sets: A check box for randomizing the row order of resultant choice sets. A row corresponds to a set in the resultant choice sets.

• 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.
