An application note on ProbOnto 1.0 has been accepted for publication in Bioinformatics!

ProbOnto stands for 'Ontology and Knowledge Base of Probability Distributions' and has following features:
  1. Over 80 uni- and multivariate distributions and alternative parameterisations.
  2. Probability density or mass functions and where available cumulative distribution, hazard and survival functions.
  3. Supports encoding of univariate mixture distributions.
  4. Over 130 relationships and re-parameterisation formulas.
  5. Related quantities such as mean, median, mode, variance.
  6. Parameter and support/range definitions and distribution type.
  7. Latex and R code for mathematical functions.
ProbOnto has been in use in PharmML since version 0.7.1.
