probability distribution

noun

, Statistics.

1. a distribution of all possible values of a random variable together with an indication of their probabilities.

probability distribution

1. A function of a discrete random variable (that is, a variable whose values are obtained from a finite or countable set) yielding the probability that the variable will have a given value.
2. Also called probability density

Word History and Origins

Origin of probability distribution¹

First recorded in 1935–40

Example Sentences

However, when simulations of a physical system using tried-and-true scientific techniques are available, researchers get a model of its probability distribution for free.

From Science Daily

The MIT team's insight is that this probability distribution also defines a generative model upon which a classifier can be constructed.

From Science Daily

The researchers have fed all the variables into the models, and developed a probability distribution for how conditions might develop in the future.

From Science Daily

This is then used to generate a probability distribution function which consists of all the feasible and infeasible solutions that are within the constraints of the COP.

From Science Daily

Next, the post-processing method transforms the infeasible solutions into feasible ones, leaving the probability distribution with only feasible solutions.
