Appendix 2Summary of Distributions
Included here are two tables, Table A2.1 for continuous distributions and Table A2.2 for discrete distributions. They list, in alphabetical order, all the distributions described in this book. Their purpose is to assist the reader in shortlisting the distributions that might be considered for a given dataset.
