I am doing an ACBC study and doing a HB analysis. Price is a summed price in the design. For the HB analysis I used piecewise option - for this option I created 27 price increments (I know that is perhaps a lot).
I set the iterations to 50 000 for prelim and 50 000 for each respondent.
I have 284 respondents.
The problem is that the analysis is now taking more than 15 hours - and there is still about 4 hours left. I have a simple laptop, but it is not that old (Rizen7, 20Gig Ram, SSD).
Does anyone have any suggestions on how to either reduce the time, but still keep the price intervals? Or perhaps make use of a faster computer?
I was thinking of splitting the sample into for instance regional groups or some kind a sub-sample that makes sense, and then running 4 or 5 smaller HB analysis on each sub-sample - perhaps the combined time of smaller groups will be less than this?
