  1. Independence (probability theory)

    In probability theory , to say that two event probability theory event s are independent intuitively means that the occurrence of one event makes it neither more nor less probable that the other occurs. For example The event of getting a 6 the first time a die is rolled and the event of getting a 6 the second time are independent . By contrast, the event of getting a 6 the first time a die is rolled and the event that the sum of the numbers seen on the first and second trials is 8 are not independent.

  1. Contiguity (probability theory)

    In probability theory , two sequences of probability measure s are said to be contiguous if asymptotically they share the same support measure theory support . Thus the notion of contiguity extends the concept of absolute continuity to the sequences of measures. The concept was originally introduced by harvtxt Le Cam 1960 as part of his contribution to the development of abstract general asymptotic theory in mathematical statistics . Le Cam was instrumental during the period in the development of abstract general asymptotic theory in mathematical statistics.

  1. Probability Theory as Extended Logic

    notability date December 2011 Probability Theory as Extended Logic is a foundation of probability theory developed by Edwin Jaynes in his book, Probability Theory The Logic of Science . ref Edwin Jaynes, Probability Theory The Logic of Science , 1995 ref The development expands classical logic to reason about uncertain information, which eventually results in the development the laws of probability ... a morbid infection that is today spreading in a way that threatens the very life of probability theory, and requires immediate surgical removal.

Thus, we have shown that probability theory arises naturally out of the construction ... properties of a system of plausible reasoning, and proceeds to derive an axiomatization of probability theory using various mathematical and logical techniques. Jaynes developments place particular emphasis ... sets. As a simple example, consider the probability of a given integer being even. Jaynes points out that we can justify any probability within 0,1 by selecting an appropriate construction of the infinite ... the reasoning system, eventually arriving at a set of axioms identical to those in probability theory.

  1. Copula (probability theory)

    In probability theory and statistics , a copula can be used to describe the Dependent and independent variables dependence between random variable s. Copulas derive their name from Copula linguistics linguistics . The cumulative distribution function of a random vector can be written in terms of marginal cumulative distribution function distribution function s and a copula. The marginal distribution functions describe the marginal distribution of each component of the random vector and the copula describes the dependence structure between the components. Copulas are popular in statistical applications as they allow one to easily model and estimate the distribution of random vectors by estimating marginals and copula separately. There are many parametric copula families available, which usually ... leq x math are continuous functions.

  1. Impossible event

    In the mathematics of probability , an impossible event is an Event probability theory event A with probability zero, or Pr A     0. ref Tannenbaum & Arnold, p. 468 Citation needed date September 2010 ref See in particular almost surely . An impossible event is not the same as the stronger concept of logical impossibility . For any continuous probability distribution the probability of any single elementary event is  0, yet the event is not logically impossible as an event outside the distribution. For instance, the probability of hitting any specific point on a dart board, let s say a square in Cartesian coordinates &minus 10,  10   ×   &minus 10,  10 and the point 4.5678,  &minus 8.4568 , is  0, because there is an Uncountable set uncountably infinite number of points on the board. In contrast, hitting a point outside of the space considered is logically impossible.

  1. Elementary event

    dablink In computer science an atomic event refers to an atomic operation Expert subject probability date June 2011 In probability theory , an elementary event probability theory event or atomic event is a Singleton mathematics singleton of a sample space . An outcome is an element of a sample space. An elementary event is a set containing exactly one outcome, not the outcome itself. However, elementary events are often written as outcomes for simplicity when the difference is unambiguous. The following are examples of elementary events All sets k , where k     N if objects are being counted and the sample space is S 0, 1, 2, 3, ... the natural numbers . HH , HT , TH and TT if a coin is tossed twice. S HH, HT, TH, TT . H stands for heads and T for tails. The real numbers , and the elementary events, are all sets x , where x     R if X is a normal distribution normally distributed random variable and S     &minus ,  . This example shows that, because they are all zero, the probabilities assigned to atomic events do not determine a continuous probability distribution . Elementary events may have probabilities that are strictly positive, zero, undefined, or any combination thereof. For instance, any discrete random variable discrete probability distribution is determined by the Probability probabilities it assigns to what may be called elementary events. In contrast, all elementary events have probability zero under any continuous random variable continuous .... Under the measure theory measure theoretic definition of a probability space , the probability of an elementary event need not even be defined, since mathematicians distinguish between the sample ... also Atom measure theory References Pfeiffer, Paul E. 1978 Concepts of probability theory .

  1. Complementary event

    In probability theory , the complement of any event probability theory event A is the event not  A , i.e. the event that A does not occur. The event A and its complement not  A are mutually exclusive and Collectively exhaustive events exhaustive . Generally, there is only one event B such that A and B are both mutually exclusive and exhaustive that event is the complement of A . The complement of an event A is usually denoted as math A prime math , math A c math or math overline A math . Simple examples A coin is flipped and one assumes it cannot land on its edge. It can either land on heads or on tails Because these two events are complementary, we have math Pr mathrm heads Pr mathrm tails 1. math Three plastic balls are in a bag. One is blue and two are red. Assuming that each has an equal chance of being pulled out of the bag, math Pr mathrm blue 1 3 mbox and Pr mathrm red 2 3. math Example of the utility of this concept Suppose one throws an ordinary six sided die eight times. What is the probability that one sees a 1 at least once? It may be tempting to say that Pr 1 on 1st trial or 1 on second trial or ... or 1 on 8th trial Pr 1 on 1st trial Pr 1 on second trial ...

The technique is wrong because the eight events whose probabilities got added are not mutually exclusive. Instead one may find the probability of the complementary event and subtract it from 1, thus Pr at least one 1 1 &minus Pr no 1 s 1 &minus Pr no 1 on 1st trial and no 1 on 2nd trial and ... and no 1 on 8th trial 1 &minus Pr no 1 on 1st trail × Pr ... dl free 0072549076 79746 ch04 p175.pdf Complementary events free page from probability book of McGraw Hill DEFAULTSORT Complementary Event Category Probability theory ca Esdeveniment contrari eu Gertakizun ... 6 1 &minus 5 6 sup 8 sup 0.7674...
