This function computes the quantiles of the full-tail gamma with the input sample data.
Usage
qFTG(p, threshold, scale, shape, interval)
Arguments
p
Probability.
threshold
Minimum value of the tail.
scale
Scale parameter.
shape
Shape parameter.
interval
a vector containing the end-points of the interval to be searched for the minimum.
Value
Gives the quantiles of the FTG. The length of the result is determined by the length of x.
