Exempel på hur man kan använda ESTIMATOR i en mening

• 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.
• In estimation theory, the root-mean-square deviation of an estimator measures how far the estimator strays from the data.
• However, a biased estimator with a small variance may be more useful than an unbiased estimator with a large variance.
• In statistics, the Gauss–Markov theorem (or simply Gauss theorem for some authors) states that the ordinary least squares (OLS) estimator has the lowest sampling variance within the class of linear unbiased estimators, if the errors in the linear regression model are uncorrelated, have equal variances and expectation value of zero.
• In statistics, the mean squared error (MSE) or mean squared deviation (MSD) of an estimator (of a procedure for estimating an unobserved quantity) measures the average of the squares of the errors—that is, the average squared difference between the estimated values and the actual value.
• So if δ(X) is some estimator of an unobserved parameter θ given a vector of observables X; and if T(X) is a sufficient statistic for θ; then an improved estimator, in the sense of having a smaller expected loss L, can be obtained by calculating.
• In order for the absolute deviation to be an unbiased estimator, the expected value (average) of all the sample absolute deviations must equal the population absolute deviation.
• The mean squared error of an estimator is the expected value of the square of its deviation from the unobservable quantity being estimated of θ.
• Bayesian probability, Bayes' theorem, and Bayes estimator, concepts in probability and statistics named after Thomas Bayes.
• Tippett, as an estimator which tends to be less influenced by the extreme observations which typify special-causes.
• Certain Hadamard matrices can almost directly be used as an error-correcting code using a Hadamard code (generalized in Reed–Muller codes), and are also used in balanced repeated replication (BRR), used by statisticians to estimate the variance of a parameter estimator.
• used a rate-optimal estimator of mutual information to explore this controversy, observing that the optimal hash-based estimator reveals the compression phenomenon in a wider range of networks with ReLu and maxpooling activations.
• Traditionally, statisticians have evaluated estimators and designs by considering some summary statistic of the covariance matrix (of an unbiased estimator), usually with positive real values (like the determinant or matrix trace).
• Pollution has been worsening for nitrogen and phosphorus, though turbidity has improved, as shown in this table of important (ie slope direction probability over 95% and RSKSE over ±1% pa) improvements, or deteriorations (-) in relative seasonal Kendall slope estimator (RSKSE) trends (% per year).
• Thorne was educated at the Thomas Rawlins School in Quorn, He left school at age 15 and became an estimator for a glass factory while practising snooker in Loughborough and then Leicester's snooker halls.
• Since wavelet transform has the ability to decompose complex information and patterns into elementary forms, it is commonly used in acoustics processing and pattern recognition, but it has been also proposed as an instantaneous frequency estimator.
• This has to be computed empirically since the estimator variances are not likely to be analytically possible when their mean is intractable.
• Ridge regression was developed as a possible solution to the imprecision of least square estimators when linear regression models have some multicollinear (highly correlated) independent variables—by creating a ridge regression estimator (RR).
• Also, these estimators are weakly consistent and plugging them into the SE estimator makes it also weakly consistent.
• He was a project estimator and manager for the Joseph Linteau & Sons company (1992–1993) and also a manager for Magasin Rona in Saint-Raymond-de-Portneuf (1986–1992).
