Goal It is your job to predict the sales price for each house. For each Id in the test set, you must predict the value of the SalePrice variable. Metric Submissions are evaluated on [Root-Mean-Squared-Error](https://en.wikipedia.org/wiki/Root-mean-square_deviation) (RMSE) between the predicted value and the observed sales price. (Taking logs means that errors in predicting expensive houses and cheap houses will affect the result equally.) Submission file format The file should contain a header and have the following format: Unique_idx price 15544 459000 17454 445000 21548 1057000 You can download an example submission file (sample_submission.csv) on the
