Subject [jira] [Updated] (MATH-784) Javadoc of AbstractLeastSquaresOptimizer.guessParametersErrors() is too vague
Date Fri, 04 May 2012 12:44:50 GMT

     [ https://issues.apache.org/jira/browse/MATH-784?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Gilles updated MATH-784:
------------------------

    Attachment: RandomStraightLinePointGenerator.java
                StraightLineProblem.java
                AbstractLeastSquaresOptimizerTestValidation.java

Here are the code I was talking about on the ML.
You have been doing the same thing it seems...

> This bug report follows a recent discussion available [here|http://mail-archives.apache.org/mod_mbox/commons-dev/201204.mbox/%3C20120418122114.GB32074%40dusk.harfang.homelinux.org%3E].
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|http://www.itl.nist.gov/div898/strd/]
are to be used.
