Open-access software (primarily R code), related tools to enable broader application of the novel methods developed under PRIME, and additional work related to environmental mixtures methodology are shared. Questions on code can be addressed to PRIME investigators/collaborators listed on specific pages or to the PRIME Program Director, Bonnie R. Joubert.

GitHub

The NIEHS PRIME GitHub includes shared software in development, or previously developed and utilized, or expanding in a PRIME project. It also includes shared public and simulated datasets used for PRIME methods development.
