# MVt distribution class

### Description

Class `MVtDistribution`

implements multivariate t distributions using
code from package mvtnorm. For details to this implementation confer
to the references given in this package.

### Objects from the Class

Objects could in principle be created by calls to `new`

, but more
frequently you would create them via the generating function
`MVtDistribution`

.

### Slots

`img`

:Object of class

`"Reals"`

.`param`

:Object of class

`"MVtParameter"`

.`r`

:function with argument

`n`

; random number generator`d`

:the density of this distribution,

`dmvt`

`p`

:the (vectorized) function

`pmvt`

.`q`

:the (vectorized) function

`qmvt`

.`radDistr`

:an object of class

`AbscontDistribution`

with density*dim * choose((dim+df-1)/2, (df-1)/2) * x ^{dim-1} * df^(-dim/2) * (1+x^2/df)^{-(dim+df)/2}*`.withArith`

:FALSE

`.withSim`

:FALSE

`.logExact`

:TRUE

`.lowerExact`

:TRUE

`Symmetry`

:object of class

`"EllipticalSymmetry"`

about center`loc`

; used internally to avoid unnecessary calculations.

### Extends
