Dear All,
I'd like to fit a kind of logistic model to small data-set using nonlinear
least-squares regression. A transcript of R-script are reproduced below.
Estimated B and T (the model's coeff, herein B=-8,50 and T=5,46) seem
appropriate (at least visually) but are quite diff from those
Your B coefficient differs by a suspicious-looking factor of 2.30... (ln(10).
Does SPSS log() mean log10 or ln? R log(x) uses ln(x).
