Package 'TukeyGH77'

Title: Tukey g-&-h Distribution
Description: Density, cumulative density, quantile and simulation of the 4-parameter Tukey g-and-h (1977) distributions. The quantile-based transformation (Hoaglin 1985 <doi:10.1002/9781118150702.ch11>) and its reverse transformation, as well as the letter-value based estimates (Hoaglin 1985).
