I need to find the parameters a,b,d,g,h,i that best fit the "q" function
q = (a + bt + dE^(gt))(1 - x + h + i*t)
but that function depends on the values of "x" and "t" , I have a list of pairs. this is the data I used
Seems it doesn't fit really
sol = NonlinearModelFit[ datosw, (a + b t + d E^(g t)) (1 - x + h + i*t) , {a, b, d, g, x, h, i}, t] Plot[(sol // Normal), {t, 0, 60}, Epilog -> Point /@ datosw, PlotRange -> {0, .08}]
