dst: Density function of sphered Student's t distribution

Description

Evaluates probability density function of sphered Student's t distribution on nu degrees of freedom. This is just the standard Student's t distribution rescaled to have unit variance.

Usage

dst(x, nu = 3)

Arguments

x

Where to evaluate the density

nu

The degrees of freedom

Value

The appropriate probability density.
