Sensitivity (true positive rate) is the probability of a positive test result, conditioned on the individual truly being positive. Specificity (true negative rate) is the probability of a negative test result, conditioned on the individual truly being negative. If the true status of the condition cannot be known, sensitivity and specificity can ...
211 is a special abbreviated telephone number reserved in the North American Numbering Plan (NANP) as an easy-to-remember three-digit code to reach information and referral services to health, human, and social service organizations. Like the emergency telephone number 911, 211 is one of the eight N11 codes of the North American Numbering Plan ...
Home Rule in the United States. Home rule in the United States relates to the authority of a constituent part of a U.S. state to exercise powers of governance; i.e.: whether such powers must be specifically delegated to it by the state (typically by legislative action) or are generally implicitly allowed unless specifically denied by state ...
The estimate value of 2 for the intercept is the mean value of the word recall when the drug dose is 0. The estimate value of 4 for the drug dose indicates that for a 1-unit change in drug dose (from 0 to 1) there is a 4-unit change in mean word recall (from 2 to 6). This is the slope of the line joining the two group means.
1 ♠ – 2 ♣ 2 ♠ – 2NT. Forcing to game, with balanced hand and a good club suit. 1 ♠ – 2 ♣ 2 ♦ – 3 ♣ Forcing, unless the partnership has agreed that this is an exception to the "2/1 rule." 1 ♦ – 2 ♣ Forcing for one round only (as in Standard American), except in the variant of 2/1 where this sequence is game forcing as ...
Big O notation is a mathematical notation that describes the limiting behavior of a function when the argument tends towards a particular value or infinity. Big O is a member of a family of notations invented by German mathematicians Paul Bachmann, [1] Edmund Landau, [2] and others, collectively called Bachmann–Landau notation or asymptotic ...

which is exact for polynomials of degree 2n − 1 or less. This exact rule is known as the Gauss–Legendre quadrature rule. The quadrature rule will only be an accurate approximation to the integral above if f (x) is well-approximated by a polynomial of degree 2n − 1 or less on [−1, 1].
