So again, we have a variable name called X, we've assigned that our dataframe, and we've now gone ahead and specifically declared which columns of our data we want to belong to this value of X. This says that this specific function is looking for a value of something greater than 20, or equal to or greater than 20. For subsequent profiles, uncomment only the relevant seed setting line.

Fixed various compatability issues that had accumulated over the last several years. This project helps us deeply understand how conjoint analysis gets consumers preference and segmentation, and how to simulate market to maximize profit But I would love to hear your thoughts about it. And now I'm going to generate a linear regression model, which really brings us full circle for the course, and we'll fit those values, and so ultimately this is going to produce a multiple regression.
