Description Objects from the Class Slots Extends Methods Author(s) See Also Examples

This class provides objects representing scaled *t* distributions.

Objects can be created by calls of the form `new("tDist", mean, var, df)`

.

`mean`

:Location parameter.

`var`

:Scale parameter.

`df`

:Degrees of freedom.

The distribution has density

*
f(x; mean, var, df) = gamma((df+1)/2)/{sqrt[var * pi * df (1 + (x - mean)^2 / (var * df))^(df + 1)] * gamma(df/2)}*

`components`

:Object of class

`"matrix"`

with columns`weight`

,`mean`

,`variance`

, and`df`

. For objects of class`"tDist"`

this matrix has only one row and`weight`

is always 1.

Class `"contDist"`

, directly.
Class `"dist"`

, by class "contDist", distance 2.

- sampleObs
`signature(dist = "tDist", size = "numeric")`

: Sample`size`

observations from`dist`

.
