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.

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.

How does a traffic estimator operate?
Traffic estimators give you an estimate of how many readers you can expect to get with a published article. All of this depends on the type of keywords you use and how well you use them in your article. Most estimators will help you generate good keywords to put into your articles as well.

Estimator?
Cost estimators are vital to the financial success of manufacturers, builders, and businesses. It’s the responsibility of an estimator to accurately access and analyze the costs to complete any given project. Estimators must factor in the cost of equipment, materials, supplies, labor, profit margin, and unexpected events, such as shipping delays and weather. The vast majority of estimators work within the construction industry, however, many are employed by manufacturers and government agencies.Estimator TrainingBecause there is no formal degree for cost estimators, some companies prefer candidates with a strong work history or a bachelor’s degree in a related field. Candidates with a bachelor’s degrees in accounting, business, construction, economics, engineering and statistics have successfully become professional estimators. Many of these fields include cost estimating classes at the undergraduate level. Government agencies and some companies require estimators to complete a voluntary professional certification. Professional estimator certifications are issued by various organizations, including the American Society of Professional Estimators, the Association for the Advancement of Cost Engineering, and the Society of Cost Estimating and Analysis. To qualify for certification, estimators must pass a written exam and have two years of work experience as an estimator.Careers as an EstimatorApproximately 60% of estimators work within the construction industry with the remainder employed by manufacturers. The most successful cost estimators can be promoted to project manager or go on to an independent consulting career. Due to the nature of the industry, estimators are required to work in the office and in the field. After performing an on-site analysis, estimators return to the office to prepare a full report and bid. In large companies, estimators may act as intermediaries between executives, subcontractors, and partners.Average Salary for EstimatorsOn average, cost estimators earn between $55,000 and $60,000 annually depending on the industry. Estimators in entry-level positions earned more than $33,000 in 2008, however, the highest-paid estimators earned $94,000. Due to growth in the construction industry and the need for additional infrastructure, job openings for cost estimators are projected to grow rapidly over the next decade. According to the Bureau of Labor Statistics, more than 55,000 new job openings for cost estimators are expected by 2018.
In the presence of heteroscedasticity OLS estimators are biased as well as inefficient?
They are still unbiased however they are inefficient since the variances are no longer constant. They are no longer the "best" estimators as they do not have minimum variance
