Dear gretl list,<br><br>I am trying to estimate a few restricted VECMs, but the estimation does fail quite often using the default switching algorithm. Actually, I just would like to know to what exactly does the following error message refer to:<br>
<br>&quot;Switching algorithm: failed<br>Exact or near collinearity encountered&quot;<br><br>I could not find any hints in the C-sources. Are the restrictions collinear or is it the high correlation between variables?<br>
<br>Thanks in advance,<br>Artur
