  2. Binomial proportion confidence interval - Wikipedia

    en.wikipedia.org/wiki/Binomial_proportion...

    The probability density function (PDF) for the Wilson score interval, plus PDF s at interval bounds. Tail areas are equal. Since the interval is derived by solving from the normal approximation to the binomial, the Wilson score interval ( , + ) has the property of being guaranteed to obtain the same result as the equivalent z-test or chi-squared test.

  3. Cutoff frequency - Wikipedia

    en.wikipedia.org/wiki/Cutoff_frequency

    The cutoff frequency is the critical frequency between propagation and attenuation, which corresponds to the frequency at which the longitudinal wavenumber is zero. It is given by The wave equations are also valid below the cutoff frequency, where the longitudinal wave number is imaginary. In this case, the field decays exponentially along the ...

  4. Half-power point - Wikipedia

    en.wikipedia.org/wiki/Half-power_point

    Half-power point. The half-power point is the point at which the output power has dropped to half of its peak value; that is, at a level of approximately -3 dB. [ 1][ a] In filters, optical filters, and electronic amplifiers, [ 2] the half-power point is also known as half-power bandwidth and is a commonly used definition for the cutoff frequency.

    en.wikipedia.org/wiki/Renormalization_group

    e. In theoretical physics, the term renormalization group ( RG) refers to a formal apparatus that allows systematic investigation of the changes of a physical system as viewed at different scales. In particle physics, it reflects the changes in the underlying force laws (codified in a quantum field theory) as the energy scale at which physical ...

    The Fourteen Points was a statement of principles for peace that was to be used for peace negotiations in order to end World War I. The principles were outlined in a January 8, 1918 speech on war aims and peace terms to the United States Congress by President Woodrow Wilson. However, his main Allied colleagues ( Georges Clemenceau of France ...
