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?
