Re: LSF method vs. averaging



Averaging the errors (with sign) would allow gross errors of opposite sign
to amount to zero average error!

For a summary of the LSF method and the rationale for using squares vs
absolute values, go to:

. . .
My question is the following: why is the LSF method considered to pro=
vide a better estimate in this particular case and also in general th=
an averaging?
