T-Mobile stated that there are a small handful of users who abuse the tethering plan by altering device software and/or the use of an Android app that masks T-Mobile's ability monitoring whether data is on-smartphone, or through smartphone mobile hotspot (tethering) by mimicking all data as on-smartphone use, with some customers abusing the ...
Suppose { P θ | θ ∈ Θ } is a parametric model and X = (X 1, …, X n) are the data sampled from this model. Let T = T(X) be an estimator for the parameter θ. If this estimator is unbiased (that is, E[ T ] = θ), then the Cramér–Rao inequality states the variance of this estimator is bounded from below:
Most frequently, t statistics are used in Student's t-tests, a form of statistical hypothesis testing, and in the computation of certain confidence intervals. The key property of the t statistic is that it is a pivotal quantity – while defined in terms of the sample mean, its sampling distribution does not depend on the population parameters, and thus it can be used regardless of what these ...
The FCC said T-Mobile suffered data breaches in 2021, 2022 and 2023 that impacted millions of ... T-Mobile will pay a $15.75 million civil penalty and has agreed to spend another $15.75 million ...
Formula weight calculator: The input is a chemical molecular formula, using the periodic-table symbols and notation, and there is a button to work out the percentages of its constituents. Astronomical calculator: The input is a date and one or multiple celestial bodies (usually the sun, moon, planets, planetoids or comets). The program ...
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 ...

In statistics, the method of estimating equations is a way of specifying how the parameters of a statistical model should be estimated.This can be thought of as a generalisation of many classical methods—the method of moments, least squares, and maximum likelihood—as well as some recent methods like M-estimators.
