Dear NLOGIT experts,

I would like to know how to use simulation command,

I've seen using "simulation", it worked.
I would like to simulate the share of change.
if price of products in Kagwa set all 2nd(=118 yen), what will happend?
How can I specify the command for this simulation?
Your kind suggestion would be greatly appreciated.
