Weighting the data in Simulation

Question

Hello team,

I had a query if we can weight the utility data in simulator.

For e.g. in ideal world the share of Toyota is 30%, Ford is 35% and Chevrolet is 35%.
But when I generate the utility scores I get a different share of preference.
Can I weight the data to arrive at the ideal world scenario?

If not, Is there any other way to do that?

Yes, the simple way to adjust the shares to match target shares is to use the "External Effects" setting in the Sawtooth Software SMRT simulator.  

But, this method is not the best approach, and of course there are many pitfalls in simply adjusting shares of preference to match what you want them to be.  For a full discussion of the issues involved, and the weaknesses of the simple approach for External Effects provided by our SMRT simulator, please see:  http://www.sawtoothsoftware.com/download/techpap/externaleffects.pdf
