Hello Everybody, I am running R 2.2.0 with Windows XP i am trying to fit nonlinear differential equation to data sets which looks like this:
[SNIP]
and i need to fit these data to the following diff equation: dNdt=a*N-b*N*C, dCdt=N^2, Where a=birth rate, b=death rate and N= Current count, C= Cumulative Count. i need to fit the differential equation, solve and obtain parameters a,b. can someone help with this, Thanks Raj
Try looking at the package odesolve for solving the ode system. Woody Setzer National Center for Computational Toxicology US EPA
