Density, distribution function, quantile function and random generation for the Truncated Generalised Gamma Distribution (also in log10(x) and ln(x) space).
This small package provides the standard R distribution functions for the Truncated Generalised Gamma Distribution (see Murray, Robotham, Power (2016) [MRP]).
Included are the density, CDF, quantile function and random generator, both for the real-space TGGD and log-space TGGD.
The simplest way to install the package is to use
First, install the only dependency,
install.packages("devtools") (note there are further dependencies of this package).
Finally, install this package:
Usage details are found by accessing the help files in the package, but are identical to the standard R distribution functions (eg.
rnorm or `dpoiss``). Examples are also found in these files.
To understand why and when to use these functions, please refer to MRP.
We note in particular that the log-space forms of the functions are defined as the distributions of the log of the variates from the real-space distribution with identical parameters. This is the correct form to use if performing Bayesian analyses in which the values of the variates are uncertain with priors defined in log-space (eg. lognormal distributions).
