💡 Words with a Similar Meaning to "Conditional probability table"

Found via reverse dictionary — words that share a conceptual meaning.

WordDefinition
contingency tablenoun(statistics) A table presenting the joint distribution of two categorical variables.
conditional probabilitynounThe probability that an event will take place given the restrictive assumption that another event has taken place, or that a combination of other events has taken place. (Mathematically, the definition would be that the conditional probability of B given A is equal to the joint probability of A and B divided by the probability of A.)
conditional varianceIn probability theory and statistics, a conditional variance is the variance of a random variable given the value(s) of one or more other variables.
probability distributionnoun(statistics) A distribution of all possible values of a random variable together with an indication of their probabilities.
conditional expectationIn probability theory, the conditional expectation, conditional expected value, or conditional mean of a random variable is its expected value evaluated with respect to the conditional probability distribution.
compound probability distributionIn probability and statistics, a compound probability distribution (also known as a mixture distribution or contagious distribution) is the probability distribution that results from assuming that a random variable is distributed according to some parametrized distribution, with (some of) the parameters of that distribution themselves being random variables.
mixture distributionIn probability and statistics, a mixture distribution is the probability distribution of a random variable that is derived from a collection of other random variables as follows: first, a random variable is selected by chance from the collection according to given probabilities of selection, and then the value of the selected random variable is realized.
marginal distributionnounThe projection of a joint probability distribution onto one of its component random variables.
f distributionnoun(statistics, probability) A probability distribution of the ratio of two variables, each with a chi-square distribution; used in analysis of variance, especially in the significance testing of a correlation coefficient (R squared).
quantile functionIn probability and statistics, the quantile function outputs the value of a random variable such that its probability is less than or equal to an input probability value.
logistic regressionIn statistics, the logistic model (or logit model) is a statistical model that models the log-odds of an event as a linear combination of one or more independent variables.
probability density functionnoun(probability theory) Any function whose integral over a set gives the probability that a random variable has a value in that set.
probability mass functionnoun(mathematics) A function that gives the relative probability that a discrete random variable is exactly equal to some value.
binomial distributionnoun(probability theory, statistics) The discrete probability distribution of the number of successes in a sequence of n independent trials, each of which yields success with probability p.
cumulative distribution functionnounA function which at each point t of the sample space has as its value the probability that a given random variable is less than (or equal) t. In symbols, F_X(t)=Pr(X<t).
conditional mutual informationIn probability theory, particularly information theory, the conditional mutual information is, in its most basic form, the expected value of the mutual information of two random variables given the value of a third.
multinomial testthe statistical test of the null hypothesis that the parameters of a multinomial distribution equal specified values; it is used for categorical data.
regular conditional probabilityIn probability theory, regular conditional probability is a concept that formalizes the notion of conditioning on the outcome of a random variable.
poisson distributionnoun(statistics) Any of a class of discrete probability distributions that express the probability of a given number of events occurring in a fixed time interval, where the events occur independently and at a constant average rate; describable as a limit case of either binomial or negative binomial distributions.
covariance matrixIn probability theory and statistics, a covariance matrix (also known as auto-covariance matrix, dispersion matrix, variance matrix, or variance–covariance matrix) is a square matrix giving the covariance between each pair of elements of a given random vector.
