In this chapter we will look at the problem of fitting data to curves and estimating several parameters. For the often-occurring linear case, we can turn the procedure into a crank-turning procedure. If the dependence on the parameters is intrinsically non-linear, we will see that the problem is much harder, but general computer programs to find minima of multidimensional functions can be of considerable help.
