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: http://www.nabble.com/seemingly-unrelated-regression-tp22970572p22970572.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
