Hello,
i am trying to run  stsls from spdep, and I am getting error:

Error in solve.default(ZpZp) :
  system is computationally singular: reciprocal condition number = 0

I would get the same error in lagsarlm, but I can fix it by setting

tot.solve=1e-12

as suggested here
http://www.nabble.com/Error-in-spdep%3A-system-is-computationally-singular-tt19880274.html#a19896513

I cannot do that in stsls. I already rescaled variables to similar scale. Is
there any way to fix that?
best,
adam
