title: Java or C equivalent of MATLAB's robustfit
body: <p>MATLAB has a magnificent <a href="http://www.mathworks.com/help/toolbox/stats/robustfit.html" rel="nofollow"><code>robustfit</code></a> function that solves the problem of excluding outliers with linear regression fitting. Is there anything similar written in Java or C (or in language X that could be adopted)?</p>
