Logistic Reggresion

[parisse]

Online help example is misleading. Should be e.g.
Pcumul,Pinstant,Ptotal,Pinstantmax,tmax,R:=logistic_regression([2.,3.,4.,5.,4.5],0.0,4.0)
Input signification: cumulated production estimated at time 0: 4, instant production at times 0, 1, 2, 3, 4: 2,3,4,5,4.5
If you plot Pinstant from x=0 to 10 you will see a nice Hubbert curve.
