Document default seeding #15

Open NeuroShepherd opened 1 year ago

NeuroShepherd commented 1 year ago

The current default random seeding approach is to set the seed for each run as equal to the run number, e.g. run number 5 includes set.seed(5). This should be clearly documented in at least two places IMO:

  1. In a vignette
  2. Directly in the app, possibly as a modal or hover textbox

See section 4 of this article for discussion on seeding https://onlinelibrary.wiley.com/doi/10.1002/sim.8086

R uses Mersenne-Twister as default which some people consider to be good enough, and some call for a replacement method https://arxiv.org/pdf/1910.06437.pdf
