Dear All:

 

I am trying to use the gstslshet function to generate the estimate the sarar
model. However, there is an error occur as following:

 

Error in solve.default(crossprod(reg)) : 

  system is computationally singular: reciprocal condition number =
4.38039e-25

 

 

Is there anyone ever met the same problem? 

 

The data is OK when I use it for the GM/IV test, but fail in the ARAR test.

 

Any help is deeply appreciated.

 

Thanks

 

Joshua
