I am trying to do 2 things:
· estimate a logit model on the fly using individual CBC responses
· estimate and display the choice probabilities for the options comprising a fixed task
I appreciate the response here: https://sawtoothsoftware.com/forum/9792/possible-way-to-do-conjoint-on-the-fly?show=9792#q9792
indicating that there would be too little information to estimate stable CBC utilities on the fly. However, for research purposes (my PhD), I want to proceed with this.
If I have estimated (and stored) the utilities for each attribute then the calculation of the choice probabilities seems feasible, but is on-the-fly CBC logit estimation impossible in ssiweb (I have v8, imminently v9)?
Alternatively, does anyone have a suggestion regarding how I could automate the retrieval from the admin module - I have already written code in Stata to estimate the logit model & choice probabilities for each respondent ex post. It is the real time estimation/display I seek.
When I say "real time", it can happen after they complete the survey, it just needs to be quickly afterwards - to show the respondent their choice probabilities.
