Re: [R] solving system of equations involving non-linearities

Many thanks, BBsolve works like a charm. First I thought I should use the squares of the equations because BBsolve would use some minimization objective function anyway but it actually only works if I don't use the squared equations. I'll check the documentation if I find something about the

[R] solving system of equations involving non-linearities

Hi, I would appreciate if someone could help me on track with this problem. I want to compute some parameters from a system of equations given a number of sample observations. The system looks like this: sum_i( A+b_i0 A+b_iC+d_i) = x sum_i( C+d_i0 C+d_iA+b_i) = y sum_i( exp(E+f_i) * ( A+b_i0
