MarginalDistribution
MarginalDistribution[dist, k]
represents a univariate marginal distribution of the k
coordinate from the multivariate distribution dist.
MarginalDistribution[dist, {k1, k2, ...}]
represents a multivariate marginal distribution of the
coordinates.
DetailsDetails
- The distribution dist can be either a discrete or continuous multivariate distribution.
- For a discrete multivariate distribution dist with PDF
, the PDF of MarginalDistribution[dist, {k1, ..., km}] is given by
where
. - For a continuous multivariate distribution dist with PDF
, the PDF of MarginalDistribution[dist, {k1, ..., km}] is given by
where
. - MarginalDistribution can be used with such functions as Mean, CDF, and RandomVariate, etc.
