For example, an auditor may: physically examine inventory as evidence that inventory shown in the accounting records actually exists (existence assertion); inspect supporting documents like invoices to confirm that sales did occur (occurrence); arrange for suppliers to confirm in writing the details of the amount owing at balance date as evidence that accounts payable is a liability (rights ...
In statistics, asymptotic theory, or large sample theory, is a framework for assessing properties of estimators and statistical tests.Within this framework, it is often assumed that the sample size n may grow indefinitely; the properties of estimators and tests are then evaluated under the limit of n → ∞.
In computer software testing, a test assertion is an expression which encapsulates some testable logic specified about a target under test. The expression is formally presented as an assertion, along with some form of identifier, to help testers and engineers ensure that tests of the target relate properly and clearly to the corresponding specified statements about the target.
In statistics, a sequence of random variables is homoscedastic (/ ˌ h oʊ m oʊ s k ə ˈ d æ s t ɪ k /) if all its random variables have the same finite variance; this is also known as homogeneity of variance. The complementary notion is called heteroscedasticity, also known as heterogeneity of variance.
SOFA Statistics is an open-source statistical package. The name stands for S tatistics O pen F or A ll. It has a graphical user interface and can connect directly to MySQL , PostgreSQL , SQLite , MS Access (map), and Microsoft SQL Server .
OpenIntro Statistics is an open-source textbook for introductory statistics, written by David Diez, Christopher Barr, and Mine Çetinkaya-Rundel. [ 1 ] The textbook is available online as a free PDF, as LaTeX source and as a royalty-free paperback.
Bigger domains have non-dichotomous variables and the ones with a higher level of measurement. (See also domain of discourse .) Semantically, greater precision can be obtained when considering an object's characteristics by distinguishing 'attributes' (characteristics that are attributed to an object) from ' traits ' (characteristics that are ...
Hence, referring to a "nominal confidence level" or "nominal confidence coefficient" (e.g., as a synonym for nominal coverage probability) generally has to be considered tautological and misleading, as the notion of confidence level itself inherently implies nominality already. [a] The nominal coverage probability is often set at 0.95.
