### Difference between estimate estimator?

I think, the estimate is a numerical value, wile the estimator
is a function or operator, which can be generate more estimates
according to some factors. For example (xbar) is estimator for
(meu), which can be various when the sample size in various, the
value that will be produced is an (estimate), but (xbar) is
estimator.

### What are the properties of good estimators?

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.

### Use a Free Tax Estimator from the IRS?

The best resource to consult for a free tax estimator is the
IRS. By going to the website of the IRS, you can be rest assured
that a free tax estimator is updated with the latest information.
You will get the most accurate tax refund information from a tax
estimator created by the IRS. You can also use a free tax estimator
from the IRS to anticipate how much money you will owe to the IRS.
If you anticipate owing a lot of money to the IRS, then you should
definitely use a free tax estimator to figure out the expenses.

### Differentiate estimate and estimator?

It can get a bit confusing! The estimate is the value obtained
from a sample. The estimator, as used in statistics, is the method
used. There's one more, the estimand, which is the population
parameter. If we have an unbiased estimator, then after sampling
many times, or with a large sample, we should have an estimate
which is close to the estimand. I will give you an example. I have
a sample of 5 numbers and I take the average. The estimator is
taking the average of the sample. It is the estimator of the mean
of the population. The average = 4 (for example), this is my
estmate.
