There are four main properties associated with a "good" estimator. These are:
1) Unbiasedness: the expected value of the estimator (or the mean of the estimator) is simply the figure being estimated. In statistical terms, E(estimate of Y) = Y.
2) Consistency: the estimator converges in probability with the estimated figure. In other words, as the sample size approaches the population size, the estimator gets closer and closer to the estimated.
3) Efficiency: The estimator has a low variance, usually relative to other estimators, which is called relative efficiency. Otherwise, the variance of the estimator is minimized.
4) Robustness: The mean-squared errors of the estimator are minimized relative to other estimators.

What properties should cupronickel have so it makes a good coin?
i dnt knw tell me i want to know
Why are super cooled metals good conductors?
Super cooled metals are good conductors because their super cooled properties allow them to conduct electric currents without resistance. This means no loss of energy.
What are 3 good things about a battery?
Battery are very good source of DC Supply it has following properties 1- No ripples 2- No line regulation 3- storage(it can be used during power failure).
Is it true or false that the physical properties of minerals are properties that are visually identifiable?
Only some properties are visually identifiable: color for example.
What is standard method of measurement used for?
The Standard Method of Measurement is used for the measurement of construction works. It gives guidelines as to what should be measured for various parts of the construction process. It allows for estimators to measure works in a standard format for easy preparation of a Bill of Quantities nad easy comparisson of tenders.
