At present, the group members collaborate in the elaboration of the following libraries in R. The total number of libraries are 2:

**1) DTDA: Doubly truncated data analysis. **

**2) hermite: Generalized Hermite Distribution. **

**1) DTDA: Doubly truncated data analysis**

This package implements different algorithms for analyzing randomly truncated data, one-sided and two-sided (i.e. doubly) truncated data. Two real data sets are included. It incorporates the iterative methods introduced by Efron and Petrosian (1999) and Shen (2008). Estimation of the lifetime distribution function and truncation times distributions is possible, together with the corresponding pointwise confidence limits based on bootstrap methods. Plots of cumulative distributions and survival functions are provided. Two real data sets are included: right-truncated AIDS data and doubly truncated data on quasar luminosities.
