An estimand is a quantity that is to be estimated in a statistical analysis. [1] The term is used to distinguish the target of inference from the method used to obtain an approximation of this target (i.e., the estimator) and the specific value obtained from a given method and dataset (i.e., the estimate). [2]
Estimation (or estimating) is the process of finding an estimate or approximation, which is a value that is usable for some purpose even if input data may be incomplete, uncertain, or unstable. The value is nonetheless usable because it is derived from the best information available. [ 1 ]
The VIF provides an index that measures how much the variance (the square of the estimate's standard deviation) of an estimated regression coefficient is increased because of collinearity. Cuthbert Daniel claims to have invented the concept behind the variance inflation factor, but did not come up with the name. [2]
Indicative planning was carried out by the General Planning Commission. The underlying concept behind indicative planning is the early identification of oversupply, bottlenecks and shortages so that state investment behavior can be modified in a timely fashion to reduce the incidence of market disequilibrium, with the goal being a concerted ...
The concept behind indicative planning is the early identification of oversupply, bottlenecks and shortages so that state investment behavior can be quickly modified to reduce market disequilibrium so that stable economic development and growth can be sustained.
These conditionals differ in both form and meaning. The indicative conditional uses the present tense form "owns" and therefore conveys that the speaker is agnostic about whether Sally in fact owns a donkey. The counterfactual example uses the fake tense form "owned" in the "if" clause and the past-inflected modal "would" in the "then" clause ...
His insurance initially estimated $350,000 for the house. After Vanek provided evidence of what was lost, his insurance paid twice as much, including living expenses while he relocated, and the ...
An "estimator" or "point estimate" is a statistic (that is, a function of the data) that is used to infer the value of an unknown parameter in a statistical model. A common way of phrasing it is "the estimator is the method selected to obtain an estimate of an unknown parameter". The parameter being estimated is sometimes called the estimand.
