    Composite deck boards are sold in either grooved or solid sided versions. The grooved composite board is fastened with hidden deck fasteners or clips, while the solid board is typically face-screwed. Most composite deck board manufacturers produce lengths of 12, 16, or 20 feet (3.7, 4.9, or 6.1 m), 5 + 1 ⁄ 2 by 3 ⁄ 4 inch (140 mm × 19 mm).

    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.

  6. Generalized least squares - Wikipedia

    en.wikipedia.org/wiki/Generalized_least_squares

    The model is estimated by OLS or another consistent (but inefficient) estimator, and the residuals are used to build a consistent estimator of the errors covariance matrix (to do so, one often needs to examine the model adding additional constraints; for example, if the errors follow a time series process, a statistician generally needs some ...

  7. Estimator - Wikipedia

    en.wikipedia.org/wiki/Estimator

    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 ...

    en.wikipedia.org/wiki/Theil–Sen_estimator

    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.

  9. Estimation theory - Wikipedia

    en.wikipedia.org/wiki/Estimation_theory

    Estimation theory is a branch of statistics that deals with estimating the values of parameters based on measured empirical data that has a random component. The parameters describe an underlying physical setting in such a way that their value affects the distribution of the measured data.
