Here are the steps to follow in order to obtain the
beta regression parameter estimates based on the median modified score function
proposed in Kenne Pagui et al. (2017):
1- Download the repository mbrbetareg on your own computer
2- Set the working directory on the terminal where there is the mbrbetareg repository
3- Compile the C code by typing the following command line on the terminal:
R CMD SHLIB mod1.c
4- Open the file examples.R for the numerical example on beta regression
The mbrbetareg implementation has been written by Euloge Clovis Kenne Pagui (kenne@stat.unipd.it) and Nicola Sartori (sartori@stat.unipd.it) From the University of Padova.
