    Conjoint Analysis

    I have 10 attributes with three factors each. I have used orthogonal design to create different cards/scenarios for these attributes. However, I have used conjoint analysis to analyse my results base on these different attributes. My question is: Is there a way I can use conjoint analysis to run...

    Choice-based conjoint (CBC) - randomized design

    I need some advice re/ randomized designs in CBC: In my CBC, I have n = 220 and 10 pair-wise comparisons, i.e., each respondent evaluates 20 choice options in 10 choice tasks. Each choice options has 5 attributes á 3 levels. In my pre-study, I used a d-optimal fractional design generated by...

    Conjoint analysis: bias due to no-choice option and linear attribute

    At the moment I am analysing survey data using Bayesian estimation in R (bayesm package) For my analysis, I have included a no-choice option (NoneOpt) that is coded as a series of zeros. However, I also have a price attribute (Delivery.costs). What I actually want to do is keep the price...

    [Conjoint Analysis] Measuring (cognitive) cost functions instead of value functions?

    Hello :wave:, usually one uses Conjoint Analysis, like in my case ACBC (Adaptive Choice Based Conjoint) in order to measure preferences and estimate utility or value functions. There are a number of attributes and attribute levels that provide value and a price (usually providing negative...

    Use of holdout cases generated in SPSS in STATA

    I am working on consumer preferences for fish, using conjoint analysis. My experimental design was generated in spss using orthogonal design, but my analysis has to be done in STATA. I need clarification if STATA will recognize the holdout cases that would have been used to validate the model in...

    Choice Based Conjoint -MNL

    Is it possible to run a Choice Based Conjoint analysis with SPSS? Otherwise if not possible would it be the same running a Multinomial Logistic regression? Does MLN provide the same info of Conjoint analyses (attributes importance, simulation of preference etc) Thanks in advance, Fabio

    using utilities of different attribute levels (from conjoint analysis) in regression?

    In short, I am trying to measure factors influencing an intention-to-purchase a product, with use of a regression. However, some of my constructs were measured with conjoint analysis and resulted in a couple of variables with utility values for all of them. What I mean is that e.g. if I have...
