Joint distributions, the uncertainty principle and positive distributions
Mathematical Structures in Computer Science, 2014We examine the construction of joint probabilities for non-commuting observables. We show that there are indications in standard quantum mechanics that imply the existence of conditional expectation values, which in turn implies the existence of a joint distribution.

Joint Probability Distributions
2011In Chapters 3 and 4, we studied probability models for a single random variable. Many problems in probability and statistics lead to models involving several random variables simultaneously. In this chapter, we first discuss probability models for the joint behavior of several random variables, putting special emphasis on the case in which the ...

Joint Distributions: Continuous
1989In Lesson 4, Part II, we saw traditional examples of continuous CDFs for one real valued random variable restricted to those cases for which the CDF was the Riemann integral of its PDF. Extending this fundamental theorem of integral calculus to Lebesgue integration involves a long array of details which we leave to such texts.

On the Joint Distribution of Observables
Foundations of Physics, 2000A general algebraic system M is considered with two binary operations. The family of all measurable functions with values in the unit interval is a motivating example. A state is a morphism from M to the unit interval, an observable is a morphism from the family of Borel sets to M. A joint distribution of two observables is constructed.

Applications of Joint Distributions
2003This Chapter presents two applications of joint fuzzy probability distributions discussed in Chapter 10. In the next section we have an application of a joint fuzzy discrete probability distribution followed by a discussion of fuzzy reliability theory which is an application of joint fuzzy continuous probability distribution.

Continuous Joint Distributions
1993The joint distribution of a pair of random variables X and Y is the probability distribution over the plane defined by $$P\left( B \right) = P\left( {\left( {X,Y} \right) \in B} \right)$$ for subsets B of the plane. So P(B) is the probability that the random pair (X, Y) falls in the set B.
