Design choice sets for DCEs.
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.
