How can price elasticity of demand for some data help in determining a decision making process in a future pricing policy? I have some data that I want to analyze. I am given prices and demand for different products over a period of time. And I would like to use the price elasticity data to get some answers (or maybe other methods?). I would appreciate any ideas on how to go about approaching this problem. I was thinking about performing a regression analysis, but, according to the data that I have, I don't think demand only depends on the price, given the fact that the prices given are mostly stable, and the demand fluctuates a lot.
