In investment, an annuity is a series of payments made at equal intervals. [1] Examples of annuities are regular deposits to a savings account, monthly home mortgage payments, monthly insurance payments and pension payments.
A Horn formula is a propositional formula formed by conjunction of Horn clauses. Horn satisfiability is actually one of the "hardest" or "most expressive" problems which is known to be computable in polynomial time, in the sense that it is a P -complete problem. [ 2 ]
Pearson's correlation coefficient, when applied to a sample, is commonly represented by and may be referred to as the sample correlation coefficient or the sample Pearson correlation coefficient. We can obtain a formula for r x y {\displaystyle r_{xy}} by substituting estimates of the covariances and variances based on a sample into the formula ...

For example, the formula + = is satisfiable because it is true when = and =, while the formula + = is not satisfiable over the integers. The dual concept to satisfiability is validity ; a formula is valid if every assignment of values to its variables makes the formula true.
The name of this formula stems from the fact that is the twentieth formula discussed in Kuder and Richardson's seminal paper on test reliability. [1] It is a special case of Cronbach's α, computed for dichotomous scores. [2] [3] It is often claimed that a high KR-20 coefficient (e.g., > 0.90) indicates a homogeneous test. However, like ...
The principle can be viewed as an example of the sieve method extensively used in number theory and is sometimes referred to as the sieve formula. [ 4 ] As finite probabilities are computed as counts relative to the cardinality of the probability space , the formulas for the principle of inclusion–exclusion remain valid when the cardinalities ...
A liability is a present obligation of an entity to transfer an economic benefit (CF E37). Common examples of liability accounts include accounts payable, deferred revenue, bank loans, bonds payable and lease obligations. Equity accounts are used to recognize ownership equity. The terms equity [for profit enterprise] or net assets [not-for ...
