't()' function for calculating GEV quantities

Usage

gev_t_function(x, location, scale, shape)

Arguments

x: Argument of the function; vectorized.
location: Location parameter; numeric.
scale: Scale parameter; positive numeric.
shape: Shape parameter; numeric. Also the extreme value index, so that shape > 0 is heavy tailed, and shape < 0 is short-tailed.

Value

A vector of the t function evaluated.

Note

The shape parameter is not vectorized. This function is only intended to be used when location, scale, and shape are scalars.
