First, you need to get the utilities out of SMRT into the right format. Within SMRT, go to Run Manager, select Export, and under "Save as Type" select "Generic Conjoint File (*.hbu)". Try uploading that utility file (*.hbu format).

SMRT converts the group-based utility information into pseudo individual-level utilities. If you are interested regarding the math for that, it is described in the SMRT manual, under the topic "How the simulator uses latent class data" (it's one of the Appendices in the SMRT manual).

Essentially, we create a weighted average of the utilities from the groups for each respondent, where the weights are the probabilities of membership that each respondent belongs in each group. So, if I am 60% likely to belong to group 1 and 40% likely to belong to group 2, then my individual-level utilities are given by taking .6 times the utilities from group 1 + .4 times the utilities for group 2.

Pseudo individual-level Latent Class utilities developed in this way are generally considered inferior to HB utilities as developed under the CBC/HB system.

I cannot use the SMRT program as my university has no license for it (only for SSI Web, HB and LC) (University of Groningen, the Netherlands). This analysis is for my master thesis.

I used the .hbu output of the HB program as input in the online simulator. This worked fine. I received share of preference's in the online similar that were equal to the one I calculated myself in excel. However, apparently I needed to use a different .hbu output?

I already calculated these pseudo individual-level utilities in excel to be able to calculate the hit rate of the model. So in theory, I would be able to upload these to the online simulator. Can i save them in excel as .csv and upload this in the online simulator? However, again, there is the .label/ .xml file for the labels I do not have....

I already calculated share of preference's in excel and did sensitivity analysis. However, I would like to use the online simulator because of the Randomized First Choice rule, which seems like to much work to compute in excel.

Hope you can give me more information on how to proceed. Thanks!
