[Scilab-users] errors (uncertainties) in non-linear least-squares fitting parameters

I have successfully fitted straight lines to my avian mortality Monte-Carlo simulation model (function of turbine size and wind speed distributions):
f(x) = pi (x+p4) with p1 for 7, p2 for 6 and p3 for 5 m/s mean wind speed
p1 = 0.3930457
p2 = 0.3492537
p3 = 0.2987269
p4 = 4.058154
But, sorry, I do not manage to derive the errors (uncertainties) in the parameters. I know I need the Jacobian, but have been unable to code it in Scilab.
Can you help?
Best greetings
Heinz
BTW, these bird fatalities are far too large when compared to observations: as a next modelling step, I need to introduce avoidance factors.....
