# Conditional Multivariate Normal Distribution

### Description

Computes the distribution function of the conditional multivariate normal, [Y given X], where Z = (X,Y) is the fully-joint multivariate normal distribution with mean equal to `mean`

and covariance matrix `sigma`

.

### Arguments

`lower` |
the vector of lower limits of length n. |

`upper` |
the vector of upper limits of length n. |

`mean` |
the mean vector of length n. |

`sigma` |
a symmetric, positive-definte matrix, of dimension n x n, which must be specified. |

`dependent.ind` |
a vector of integers denoting the indices of the dependent variable Y. |

`given.ind` |
a vector of integers denoting the indices of the conditioning variable X. |
