stand_t_dens {sstvars}R Documentation

The density function of the univariate t distribution with zero mean and unit variance

Description

stand_t_dens calculates the density of the univariate t distribution with zero mean and unit variance, described, for example, in Virolainen (2025).

Usage

stand_t_dens(y, nu)

Arguments

y

a numeric vector containing the values at which the density is to be evaluated.

nu

the degrees of freedom parameter value, a numeric scalar strictly larger than two.

Details

See Virolainen (2025) and the references therein, for example, for the details of the density function of t-distribution with zero mean and unit variance (assume the skewness parameter value is zero to obtain the non-skewed version of the t-distribution).

Value

Returns a numeric vector of the same length as y containing the density values.
