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? -- View this message in context:
