| katybo | oops, I thought it was a statistic. |
| topdan | Statistic = Sample (S=S) Parameter = Population (P=P) |
| geofin | From Wikipedia: "An "estimator" or "point estimate" is a statistic (that is, a function of the data) that is used to infer the value of an unknown parameter in a statistical model." |
