... the fitting
algorithm is based on mathematical principles. Attempting to do do a
linear fit on suspected exponential data that have been transformed by
logarithm violates the principles used - "maximum likliehood" I believe it
is - because the distribution underlying each data point is no longer
normal. On a semi-log plot, especially when uncertainties may be largish,
you can really see the effect of the skewing. The use of a least squares
algorithm is not just a matter of aesthetic choice.
Gee Leigh, it surprises me that you would say this because you are usually
such a stickler for detail, and this is not just a detail, but the basis
on which the procedure is carried out.
