A cost estimate is the approximation of the cost of a program, project, or operation.The cost estimate is the product of the cost estimating process. The cost estimate has a single total value and may have identifiable component values.
An interactive electronic technical manual (IETM) is a portal to manage technical documentation. IETMs compress volumes of text into just CD-ROMs or online pages which may include sound and video , and allow readers to locate needed information far more rapidly than in paper manuals.

In statistics, an estimator is a rule for calculating an estimate of a given quantity based on observed data: thus the rule (the estimator), the quantity of interest (the estimand) and its result (the estimate) are distinguished. [1] For example, the sample mean is a commonly used estimator of the population mean. There are point and interval ...
(which is inconsistent in this framework) and instead use a HAC (Heteroskedasticity and Autocorrelation Consistent) estimator. In the context of autocorrelation, the Newey–West estimator can be used, and in heteroscedastic contexts, the Eicker–White estimator can be used instead. This approach is much safer, and it is the appropriate path ...
For example, the midhinge minus the median is a 3-term L-estimator that measures the skewness, and other differences of midsummaries give measures of asymmetry at different points in the tail. [ 1 ] Sample L-moments are L-estimators for the population L-moment, and have rather complex expressions.
An estimator for the slope with approximately median rank, having the same breakdown point as the Theil–Sen estimator, may be maintained in the data stream model (in which the sample points are processed one by one by an algorithm that does not have enough persistent storage to represent the entire data set) using an algorithm based on ε-nets.
[1] [3] [2] The HCM has been a worldwide reference for transportation and traffic engineering scholars and practitioners, and also the base of several country-specific capacity manuals. The most-recent version, the Highway Capacity Manual, Seventh Edition: A Guide for Multimodal Mobility Analysis was released in January 2022. [4]
