It can be used to analyze any dataset that captures timestamped transitions in a discrete state space. Use cases include credit rating transitions, system state event logs etc. \n\nYou can use transitionMatrix to\n\n- Estimate transition matrices from historical event data using a variety of estimators\n- Manipulate transition matrices (generators, comparisons etc.)\n- Visualize event data and transition matrices\n- Provide standardized data sets for testing\n- Model transitions using threshold processes\n- Map credit ratings using mapping tables between popularly used rating systems \n\nKey Information\n================\n\n* Author: [Open Risk](http://www.openriskmanagement.com)\n* License: Apache 2.0\n* Code Documentation: [Read The Docs](https://transitionmatrix.readthedocs.io/en/latest/index.html)\n* Mathematical Documentation: [Open Risk Manual](https://www.openriskmanual.org/wiki/Transition_Matrix)\n* Development website: [Github](https://github.com/open-risk/transitionMatrix)\n* Project Chat: [Open Risk Commons](https://www.openriskcommons.org/c/open-source/transitionmatrix/15)\n\n**NB: transitionMatrix is still in active development.
