I am trying to run an ANOVA on my soil respiration data, but I keep getting residual sum of squares and mean square of zero. As I understand it that would mean that the model terms explain all of the variation in the response variable. That should be virtually impossible, should it not? Where do I begin troubleshooting such a problem? -- View this message in context: http://r.789695.n4.nabble.com/ANOVA-Residual-SS-and-MS-of-0-tp3548031p3548031.html Sent from the R help mailing list archive at Nabble.com.

Where do I begin troubleshooting such a problem?
1. By examining your data to see whether you have entered it correctly. 2. By reading the posting Guide at the bottom of this and every message and doing as it asks (posting a portion of your data and R code so that we can see what you did). 3. By consulting your local statistician so that she can help you better understand the nature of your problem and whether you have appropriate data and methodology to address it. -- Bert
