Sébastien Brisard updated MATH-784:
-----------------------------------

    Fix Version/s:     (was: 3.1)
                   4.0
         Assignee:     (was: Sébastien Brisard)

{color:red}
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.

> Javadoc of AbstractLeastSquaresOptimizer.guessParametersErrors() is too vague

>  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.
