'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.
