Subject [jira] [Updated] (MATH-784) Javadoc of AbstractLeastSquaresOptimizer.guessParametersErrors() is too vague
Date Tue, 29 May 2012 05:30:24 GMT


Sébastien Brisard updated MATH-784:

    Fix Version/s:     (was: 3.1)
         Assignee:     (was: Sébastien Brisard)

As far as version 3.1 is concerned, this issue is _fixed_. However, this ticket must remain
open until 4.0 is on the tracks, as some deprecated methods must be removed.

It is now recognized that the values returned by {{guessParametersErrors()}} are in fact known
as (asymptotic) standard errors. The javadoc should be made more explicit. Besides, the values
returned by this method should be tested. The reference datasets from [NIST|]
are to be used.
