Subject: [jira] [Updated] (MATH-784) Javadoc of
 AbstractLeastSquaresOptimizer.guessParametersErrors() is too vague
MIME-Version: 1.0

     [ https://issues.apache.org/jira/browse/MATH-784?page=3Dcom.atlassian.=
jira.plugin.system.issuetabpanels:all-tabpanel ]

S=C3=A9bastien Brisard updated MATH-784:
-----------------------------------

    Fix Version/s:     (was: 3.1)
                   4.0
         Assignee:     (was: S=C3=A9bastien Brisard)

{color:red}
As far as version 3.1 is concerned, this issue is _fixed_. However, this ti=
cket must remain open until 4.0 is on the tracks, as some deprecated method=
s must be removed.

> This bug report follows a recent discussion available [here|http://mail-a=
rchives.apache.org/mod_mbox/commons-dev/201204.mbox/%3C20120418122114.GB320=
74%40dusk.harfang.homelinux.org%3E]. It is now recognized that the values r=
eturned by {{guessParametersErrors()}} are in fact known as (asymptotic) st=
andard errors. The javadoc should be made more explicit. Besides, the value=
s returned by this method should be tested. The reference datasets from [NI=
ST|http://www.itl.nist.gov/div898/strd/] are to be used.
