- probability density function (detib);
- cumulative density function (petib);
- quantile function (qetib) and;
- function for generating pseudo-random numbers (retib) of the ET-IB distribution.
In addition, the etibfit function is available for parameter estimation of ET-IB distribution. This function return the maximum likelihood estimates of the parameters, a histogram of the data with the fit distribution, and goodness-of-fit measures useful for model selection.
The file "etib.R" file provide examples of functions application for selected scenarios.
