RE: (45) Straight-Line Fitting
And that is why I bought the HP-55 in 1975 as my first HP calculator because it had built-in linear regresssion! Earlier that year, I had done linear regression (ln(y) vs 1/(x+constant)) calculations on a Sharp scientific calculator with one memory register ... and I swore it was the first and last time I do linear regression in that painfull way!!!
