The following equation is a function for parameterfitting in the Reed-Frost epidemiological

model, but acquaintance with the model is not a necessity, i just need help in figuring out

how to approximate the parameter q in the following equation:

(sum (from t=0 to n-1) of C(t)C(t+1)q^C(t)/q(1-q^C(t)))-(sum (from t=0 to n-1) of

C(t)S(t+1)/q = 0

where C(t) and S(t) are discrete functions

The equation can also be seen in the following link:

You can contact me, pgoetze@ruc.dk, if you are unsure how to interpreat the equation.

Matlab and maple are at my disposal.

If you know a method for solving this problem i would be really greatful!

Ps.

This question is posted in other areas of this forum because i do not know the category of the problem, sorry!
