I was trying to do a willingness to pay using the simulator by raising the price of a product until its share of preference drops to the original value. However, after a specific price (the max price listed on my study), I get a warning saying that the simulation contains an extrapolated value, and the simulator will use straight-line projection to estimate level utility. And probably because of this, the share does not drop to the original value regarding of whatever the price increase.
Can I only use the prices specified for that particular attribute level? The pricing attribute had 3 levels (Low, Medium, and High), and I used conditional pricing with respect to another attribute with 2 levels. So in total, there were 6 prices.
