Hi to all gretl gurus. <div><br></div><div>I&#39;m currently writing some app in windows system, which uses libgretl. I&#39;ve successfully implemented function LSQ using OLS. I thought, ok, let&#39;s try Least Absolute Deviation. </div>

<div><br></div><div>I have made test sample, which calls LAD and then when things became interesting. It outputed same results as LSQ. Then I realize that MODEL holds property ( &quot;<span style="background-color:rgb(255,255,255)">errcode</span>&quot;). I checked that out and found out that it was 12. After quick reference and some source code viewing I saw it was something wrong with LAD plugin.</div>

<div><br></div><div>Does anybody know how to solve this puzzle? </div><div><br></div><div>PS: Sorry for bad english.   </div><div>-- <br>LP Simon<br>
