What is TSS = RSS+ESS ?
RSS=
1) residual sum of squares
2) regression sum of suares
ESS=
1) explained sum of squares
2) error sum of squares
Some people, e.g. R team, proposed
to solve this enigma using MSS (model sum of squares)
Does all this really important?

You beat me to it! I was just going to suggest that "Estimate" is
about the only acceptable alternative to "Model" that I can think of.
But I think/guess that "Model" is more likely to call up correct
expectations of what's to be found in that menu, for most users.
