Related to estimator: Unbiased estimator


1. a rough calculation or one based on incomplete data.
2. a statistic used to characterize the value of a population parameter. Called also estimator.
3. (es´tĭ-māt) to produce or use such a calculation or statistic.


A prescription for obtaining an estimate from a random sample of data. An estimator is a procedure, not a result, and therefore is a random variable and has a variance. For instance, an estimator of the mean weight in adult men may consist of the prescription "Add up the weights of 100 men and divide by 100." The actual outcome (the estimate) will vary from sample to sample, but one answer will not be a random variable.


/es·ti·ma·tor/ (es´tĭ-ma″ter) estimate (2).


A prescription for obtaining an estimate from a random sample of data.

Patient discussion about estimator

Q. Hi friends, I like to estimate my body fat based on my height and weight. Hi friends, I like to estimate my body fat based on my height and weight. When I enquired about this I heard about BMI. Though I understood little about it I want to know more about what is BMI and why is it useful?

A. the BMI is not a very good only helps if you are an average person. you can gain weight if you start training and still get in shape and loose fat. but it is our only cheap method...there are gyms that hold a way of measuring body fat- maybe try going to one of those?
