A. An estimate is a function of a sample of data to be drawn randomly from a population whereas an estimator is the numerical value of the estimator when it is actually computed using data from a specific sample. B. An estimator is a function of a sample of data to be drawn randomly from a. Show transcribed image text. The square provides a measure of the distance between the estimator and the true value. Therefore, the lower the MSE is, the lower on average the distance of the estimator from the true value, and the better the estimator is. For an example of such comparisons, see the lecture on Ridge estimation. Other metrics Point vs. Interval. Estimators can be a range of values (like a confidence interval) or a single value (like the standard deviation ). When an estimator is a range of values, it’s called an interval estimate. For the height example above, you might add on a confidence interval of a couple of inches either way, say 54 to 58 inches.An estimate is a function of a sample of data to be drawn randomly from a population whereas an estimator is the numerical value of the estimator when it is actually computed using data from a specific sample.

A point estimate is a single value estimate of a parameter. For instance, a sample mean is a point estimate of a population mean.
