Hi Xisco,
This concerns the formula (exponential regression) on the chart, in my opinion
it is wrong.

I think it's possible to calculate the coefficient of the exponential quite
simply in this way: 
              f(X) = B.exp(A.X)  with A = LN(LOGREG (...; ...; 1; 1)).

              For coefficient 'B' I do not know just.

In French it is LOGREG, I do not know if it has another name.

Thank you very much
