seemingly unrelated regression
Hello,
I am working on the model of seemingly unrelated regression. I came across
with the error message:
Log determinant of residual covariance: NA
Warning messages:
NAs generated in: log(x)
I have three linear models which contain 21 explanatory variables and there
are about 300 data points.
Could anyone please give some idea what is wrong with the model?
