  3. F-distribution - Wikipedia

    en.wikipedia.org/wiki/F-distribution

    In probability theory and statistics, the F-distribution or F-ratio, also known as Snedecor's F distribution or the Fisher–Snedecor distribution (after Ronald Fisher and George W. Snedecor), is a continuous probability distribution that arises frequently as the null distribution of a test statistic, most notably in the analysis of variance (ANOVA) and other F-tests.

    The Cauchy distribution, an example of a distribution which does not have an expected value or a variance. In physics it is usually called a Lorentzian profile, and is associated with many processes, including resonance energy distribution, impact and natural spectral line broadening and quadratic stark line broadening.

    The formula for the one-way ANOVA F-test statistic is =, or =. The "explained variance", or "between-group variability" is = (¯ ¯) / where ¯ denotes the sample mean in the i-th group, is the number of observations in the i-th group, ¯ denotes the overall mean of the data, and denotes the number of groups.

  8. FCurve - Wikipedia

    en.wikipedia.org/wiki/FCurve

    An FCurve (also written f-curve) is a function curve or the graph of a function.An example of a FCurve is a spline.. In the field of computer animation and especially in animation editors, e.g. Maya, an FCurve is an animation curve with a set of keyframes, which are represented as points, curve segments between keys, and tangents that control how curve segments enter and exit a key.

    Given any two local parametrizations f : V → U and f ′ : V ′→ U ′ of a regular surface, the composition f −1 ∘ f ′ is necessarily smooth as a map between open subsets of ℝ 2. [17] This shows that any regular surface naturally has the structure of a smooth manifold , with a smooth atlas being given by the inverses of local ...
