What is probabilistic arithmetic?
Probabilistic arithmetic lets you make calculations with probability distributions as conveniently as with ordinary numbers. For instance, if you know body weights are lognormally distributed and intake rates are uniformly distributed, what is the distribution of doses (intake/body weight)? Such problems are usually solved with Monte Carlo methods, but Risk Calc uses faster, semi-analytic algorithms to get the answers without random sampling. It can add, subtract, multiply, and divide distributions. If you tell it the distributions are independent of one another, itll use that information to get the best estimates possible. If you dont want to make this assumption, it will get bounds that are guaranteed to enclose the true answer. The software can also do a variety of other operations like take powers, logarithms, etc.
