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 densitynoun(probability theory) probability density function
densitynoun(physics) A measure of the mass of matter contained by a unit volume.
probability mass functionnoun(mathematics) A function that gives the relative probability that a discrete random variable is exactly equal to some value.
normal distributionnoun(statistics) Any of a family of continuous probability distributions such that the probability density function is the Gaussian function
distribution functionnoun(mathematics, physics) A function of seven variables of the form f(x,y,z,t;v_x,v_y,v_z) that gives the number of particles per unit volume in single-particle phase space.
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).

gamma distributionnoun(probability theory, statistics) Any of a family of two-parameter continuous probability distributions, of which the common exponential distribution and chi-square distribution are special cases.
probability measurenoun(mathematics) A mathematical measure on a probability space that can take on values between 0 and 1, with 0 corresponding to the empty set and 1 to the entire space.
gaussiannoun(statistics) The normal distribution.
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).
likelihoodnounThe probability of a specified outcome; the chance of something happening; probability; the state or degree of being probable.
probabilitynounThe relative likelihood of an event happening.
gaussian distributionnoun(statistics) Synonym of normal distribution.
rice distributionnoun(statistics) The probability distribution of the magnitude of a circular bivariate normal random variable with potentially non-zero mean.
