| Sep 10, 2014 at 20:21 | comment | added | Zaralynda | Yes, it's only 34 data points, so pretty easy to visually verify that it's the exact same data. Also checked that columns are set for numeric data and such. | |
| Sep 10, 2014 at 20:18 | comment | added | abaumann | No, I suspect a data error of some form. Have you tried manually inspecting your data set in the newer package? | |
| Sep 10, 2014 at 20:16 | comment | added | Zaralynda | the blue model is from the newer software package. I can't figure out from the help files which algorithm they're using, either. Can a different algorithm really explain this much variation? | |
| Sep 10, 2014 at 20:09 | comment | added | abaumann | @Zaralynda there seems to be something fundamentally wrong with the blue model. Not sure what this could be though. | |
