Basic Functions for Supporting an Implementation of Choice Experiments

Provides basic functions that support an implementation of (discrete) choice experiments (CEs). CEs is a question-based survey method measuring people's preferences for goods/services and their characteristics. Refer to Louviere et al. (2000) for details on CEs, and Aizaki (2012) for the package.

  • Modified the functions questionnaire,, mwtp, and gofm. These are also available for binary choice experiments. The functions questionnaire and handle a common base option. The function questionnaire can print choice sets without quotation marks. The function mwtp returns a matrix of replicated estimates.
  • Added a synthetic data set syn.res3 for binary choice experiments.

  • Modified the functions print.mwtp and make.dataset.

2012-05-28, version 0.2-2

  • Modified the output from the design functions. These return an object of S3 class "cedes."
  • Modified the output from the function gofm. It returns an object of S3 class "gofm."
  • Modified the argument in the function mwtp. Argument decimal.places is deleted.
  • Modified the output from the function mwtp. It returns an object of S3 class "mwtp." Structure of the output is modified.

2012-03-06, version 0.2-1

  • Modified the output from the functions or A component design.information is added to the output.
  • Modified the arguments in the functions questionnaire and Arguments nblocks, nquestions, nalternatives, and nattributes are automatically set on the basis of design.information included in the output from the design functions.
