Choice Components Analysis

Choice Components Analysis analyzes survey data on the primary determinants of option choice. These determinants are automatic and blocked selections, and, comparative evaluations between options. Habits and behavioural scripts are examples of automatic selections, while, blocked selections occur when, for example, an individual is unaware of or ignores an option. Comparative evaluations occur when options are weighed up and are implicit, for example, in option attractiveness ratings. The probability of each option’s selection from within an group of options is partitioned into component contributions for each respondent and for selection shares for the sample. From 2 to 30 options may be included in any single analysis. Choice Components Analysis is a Microsoft Excel VBA program than can be run as an Add-In or simply by double-clicking on the program and running it within Microsoft Excel.
