Error output of the switching algorithm

<div><p>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>"Switching algorithm: failed<br>Exact or near collinearity encountered"<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
