| # Dataset Name: Lew (Beam Deflection Data) |
| # |
| # Description: This is an observed/"real world" data set |
| # consisting of 200 deflections of a steel-concrete |
| # beam while subjected to periodic pressure. |
| # The experimenter was H. S. Lew of the |
| # Center for Building Technology at NIST. |
| # We here use this data to test accuracy |
| # in summary statistics calculations. |
| # |
| # Stat Category: Univariate: Summary Statistics |
| # |
| # Reference: http://www.itl.nist.gov/div898/strd/univ/lew.html |
| # |
| # Data: "Real World" |
| # 1 Response : y = beam deflection |
| # 0 Predictors |
| # 200 Observations |
| # |
| # Model: Lower Level of Difficulty |
| # 2 Parameters : mu, sigma |
| # 1 Response Variable : y |
| # 0 Predictor Variables |
| # y = mu + e |
