Optimization
Response optimization helps you identify the combination of variable settings that jointly optimize a single response or a set of responses. This is useful when you need to evaluate the impact of multiple variables on a response.
You must fit a model before you can use the response optimizer. If you want to optimize multiple responses, you must fit a model for each response separately. Response optimizer does not use the data in the worksheet. Instead, Minitab looks in the worksheet for a stored model(s) to obtain the necessary information.
