Hi Dan- The reason why the intercept is forced to be zero is because I would like to determine how well my prediction is compared to experiment. Therefore, the only point we really know is (0,0) - everything else is conjecture. Both in the excel case and the R case, the intercept is forced to be zero. In terms of your question about the regression without an intercept in R, I'm not sure what you mean. Haven't I set the intercept to be zero? Thanks! -Lance ______________________________________________ [email protected] mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
