[jira] [Updated] (MATH-1353) "EmpiricalDistribution" has various
shortcomings
[ https://issues.apache.org/jira/browse/MATH-1353?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Gilles Sadowski updated MATH-1353:
----------------------------------
Description:
(/) Class uses file IO (CM should not be concerned with data persistence)
(/) Class uses the "java.net" API (ditto)
(/) I'd think that the core functionality could be provided without supporting data loading (from a file or a URL).
(x) Data input would be via any of
* Collection
* Iterable
* Stream (Java 8)
(/) A redesign goal should be to make the class immutable.
(/) E.g. data source must be set in the constructor (rather than via a "load" method); there would thus be a one-to-one correspondence between data source and distribution instance.
