Discrete variable's values are also "disjoint," so we have the gaps in a discrete variable's probability distribution graph. While the formula for the expected value of a discrete variable may seem ...

Invariance of a random discrete distribution under size-biased permutation is equivalent to a conjunction of symmetry conditions on its finite-dimensional distributions. This is applied to ...

The course covers the probability and distribution theory needed for third year courses in statistics and econometrics.: Events and their probabilities. Random variables. Discrete and continuous ...
