unbiased estimate उदाहरण वाक्य

Producers of survey data sometimes release the average of the censored amounts to help users impute unbiased estimates of the top group.
The proficiency estimates are provided in the form of so-called plausible values, which allow unbiased estimates of differences between groups.
Multicollinearity ( as long as it is not " perfect " ) can be present resulting in a less efficient, but still unbiased estimate.
The combination of these traits makes it possible to produce unbiased estimates of population totals, by weighting sampled units according to their probability of selection.
However, the connection to sample variance and unbiased estimates could be made clearer .-- MarkSweep 18 : 36, 24 Mar 2005 ( UTC)

Suppose that a simple unbiased estimate can be constructed based on only a few observations : this defines the basic estimator based on a given number of observations.
If this is done, it is common to use n-1 as the divisor rather than n, corresponding to an unbiased estimate of the sample variance.
For example, a single observation is itself an unbiased estimate of the mean and a pair of observations can be used to derive an unbiased estimate of the variance.
For example, a single observation is itself an unbiased estimate of the mean and a pair of observations can be used to derive an unbiased estimate of the variance.
This says that the expected value of the quantity obtained by dividing the observed sample variance by the correction factor \ gamma _ 1 gives an unbiased estimate of the variance.
