  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. Binary option - Wikipedia

    en.wikipedia.org/wiki/Binary_option

    In the Black–Scholes model, the price of the option can be found by the formulas below. [27] In fact, the Black–Scholes formula for the price of a vanilla call option (or put option) can be interpreted by decomposing a call option into an asset-or-nothing call option minus a cash-or-nothing call option, and similarly for a put – the binary options are easier to analyze, and correspond to ...

  4. Binomial distribution - Wikipedia

    en.wikipedia.org/wiki/Binomial_distribution

    In probability theory and statistics, the binomial distribution with parameters n and p is the discrete probability distribution of the number of successes in a sequence of n independent experiments, each asking a yes–no question, and each with its own Boolean-valued outcome: success (with probability p) or failure (with probability q = 1 − p).

  5. Negative binomial distribution - Wikipedia

    en.wikipedia.org/wiki/Negative_binomial_distribution

    Different texts (and even different parts of this article) adopt slightly different definitions for the negative binomial distribution. They can be distinguished by whether the support starts at k = 0 or at k = r, whether p denotes the probability of a success or of a failure, and whether r represents success or failure, [1] so identifying the specific parametrization used is crucial in any ...

  6. Binomial regression - Wikipedia

    en.wikipedia.org/wiki/Binomial_regression

    If the response is a binary variable (two possible outcomes), then these alternatives can be coded as 0 or 1 by considering one of the outcomes as "success" and the other as "failure" and considering these as count data: "success" is 1 success out of 1 trial, while "failure" is 0 successes out of 1 trial.

  7. Predictive probability of success - Wikipedia

    en.wikipedia.org/wiki/Predictive_probability_of...

    Predictive probability of success (PPOS) is a statistics concept commonly used in the pharmaceutical industry including by health authorities to support decision making. In clinical trials , PPOS is the probability of observing a success in the future based on existing data.

  8. Binary regression - Wikipedia

    en.wikipedia.org/wiki/Binary_regression

    Binary regression is usually analyzed as a special case of binomial regression, with a single outcome (=), and one of the two alternatives considered as "success" and coded as 1: the value is the count of successes in 1 trial, either 0 or 1.

  9. Vertical spread - Wikipedia

    en.wikipedia.org/wiki/Vertical_spread

    The term originates from the trading sheets that were used in the open outcry pits on which option prices were listed out by expiry date & strike price, thus looking down the sheet (vertical) the trader would see all options of the same maturity. Vertical spreads can sometimes approximate binary options, and can be produced using vanilla options.
