Welcome to the blapsr project!

The blapsr package can be used for approximate Bayesian inference in survival models and generalized additive models. The theoretical framework for the methodology underlying the routines has been developed in [1] Gressani & Lambert (2018), [2] Gressani & Lambert (2020) and [3] Gressani & Lambert (2021) during my PhD thesis at the University of Louvain. It allows to fit Cox proportional hazards models and promotion time cure models (for right censored data), additive partial linear models with normal errors and generalized additive models for a response belonging to the one-parameter exponential family. Up to date the package is still in its infancy and will (hopefully!) evolve in the future. The aim of this website is to serve as a centralized platform for the blapsr software with dedicated group discussions, announcements relative to package updates, comments, examples and more.

CRAN
The Comprehensive R Archive Network (CRAN) hosts the package as from July 13th 2020 with initial version 0.5.1. Metadata on the package, license, copyright and citation information can be found at https://CRAN.R-project.org/package=blapsr.
To work with the blapsr package from CRAN, simply install the package using install.packages("blapsr") and load it in your library with library("blapsr").
R
Github
The Github repository https://github.com/oswaldogressani/blapsr hosts the in-development version of the blapsr package. Currently
the version is 0.5.1.1. Whenever the development version evolves, the fourth component will be incremented, for instance version
0.5.1.7 is a successor of, say, 0.5.1.2. More important updates will be submitted to CRAN and will affect the other three components
of the version.
To work with the blapsr package from Github, simply install the devtools package using install.packages("devtools"), then type the following command devtools::install_github("oswaldogressani/blapsr")and load it in the library. That's it, enjoy!
