Green and Krieger Software Programs

In the course of carrying out their own research, Paul Green and Abba Krieger have developed Window-based software for the following models. The quick links each take you to a short description of the program on this page.

  • Conjoint Display - A ratings-based conjoint analysis program
  • Simopt - A choice-based conjoint analysis program
  • Simact - A choice-based conjoint analysis program that includes 2-way interactions, statistical confidence intervals, and factorially designed scenarios
  • bundopt - An innovative version of TURF analysis
  • voice - A customer satisfaction model with optimality features
  • HIERmapr - A multidimensinal mapping and clustering program

This page offers links to User Manuals and FAQs (in PDF format) for all models except simact  (the user manual of which is still in preparation). In addition, two articles dealing with conjoint and tradeoff modeling are provided here:

Conjoint Display

Conjoint Display is a consumer choice simulator used to model buyersâ choices among competitorsâ products/services.  Its primary role is to enable the user to forecast market shares received by alternative suppliers, as applied to traditional (ratings type) conjoint data collection programs (which include Sawtoothâs ACA and SPSSâs full profile conjoint).

Simopt

The Simopt model is a choice-based simulator used to forecast market shares (and returns) under various strategies assumed to be adopted by one or more competitors. Unlike Conjoint Display, the Simopt model utilizes either respondent discrete choices (or alternatively, purchase likelihoods) across a set of explicit competitors.

A primary assumption of Simopt is that the input data are supplier-specific; that is, the attributes and levels can vary across suppliers.  In Simopt, there are always at least two suppliers. (The second supplier could be the "rest of the market.")

Simopt is the only choice-based simulator that is individual-specific (as opposed to using some type of data pooling across individuals).  This individuality is achieved by collecting both self-explicated data and more "global" responses to a set of choice profiles (e.g., suppliers).

Bundopt

The Bundopt model uses one of the most common sources of marketing data - pick k/n data - to determine the best bundle of items (e.g., consumer benefits, product assortments, service items, advertising message components, corporate images, product descriptions, etc.) to bring to market.

Voice

Voice is an analytical and predictive product for analyzing customer satisfaction data obtained from two or more competitive suppliers. The Voice model is typically used to measure customer satisfaction regarding products and services.  Its strategic purpose is to select those product/service attributes that will maximize the firmâs share/return, conditional upon competitive firmsâ offerings.

HIERmapr

HIERmapr is a student version of the commercial Intellicomm HierMaps program that performs two-way and multiple correspondence analysis (a perceptual mapping technique) and hierarchical clustering.
