> 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.
