  2. Frequency divider - Wikipedia

    en.wikipedia.org/wiki/Frequency_divider

    An animation of a frequency divider implemented with D flip-flops, counting from 0 to 7 in binary For power-of-2 integer division, a simple binary counter can be used, clocked by the input signal. The least-significant output bit alternates at 1/2 the rate of the input clock, the next bit at 1/4 the rate, the third bit at 1/8 the rate, etc.

  3. Sample complexity - Wikipedia

    en.wikipedia.org/wiki/Sample_complexity

    In others words, the sample complexity (,,) defines the rate of consistency of the algorithm: given a desired accuracy and confidence , one needs to sample (,,) data points to guarantee that the risk of the output function is within of the best possible, with probability at least .

  4. Binary entropy function - Wikipedia

    en.wikipedia.org/wiki/Binary_entropy_function

    Binary entropy ⁡ is a special case of (), the entropy function. H ⁡ ( p ) {\displaystyle \operatorname {H} (p)} is distinguished from the entropy function H ( X ) {\displaystyle \mathrm {H} (X)} in that the former takes a single real number as a parameter whereas the latter takes a distribution or random variable as a parameter.

  5. Potential method - Wikipedia

    en.wikipedia.org/wiki/Potential_method

    Consider a counter represented as a binary number and supporting the following operations: Initialize: create a counter with value 0. Inc: add 1 to the counter. Read: return the current counter value. For this example, we are not using the transdichotomous machine model, but instead require one unit of time per bit operation in the increment ...

  6. Calculator input methods - Wikipedia

    Note the formula on the dot-matrix line above and the answer on the seven-segment line below, as well as the arrow keys allowing the entry to be reviewed and edited. This calculator program has accepted input in infix notation, and returned the answer , ¯. Here the comma is a decimal separator.

  7. 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.

  8. Binary function - Wikipedia

    en.wikipedia.org/wiki/Binary_function

    A binary operation is a binary function where the sets X, Y, and Z are all equal; binary operations are often used to define algebraic structures. In linear algebra, a bilinear transformation is a binary function where the sets X, Y, and Z are all vector spaces and the derived functions f x and f y are all linear transformations.

  9. Sample size determination - Wikipedia

    en.wikipedia.org/wiki/Sample_size_determination

    The sample size is an important feature of any empirical study in which the goal is to make inferences about a population from a sample. In practice, the sample size used in a study is usually determined based on the cost, time, or convenience of collecting the data, and the need for it to offer sufficient statistical power. In complex studies ...
