Imagine the simple growth model x't = a x[t] (1 - c x[t]). Say I have ten experimental values at time t=0 and t = 10. How can I estimate the value of "a" and "c" using FindMinimum or some other means. I have looked at the FAQ, "How can I fit data to a model that is defined using NDSolve" (http://www.wolfram.com/support/Math/Statistics/NDSolveFit.html) but this doesn't seem to apply, since it describes the case where data is collected at various time points for a single replicate rather than at identical time points for many replicates. BTW, I have to use NDSolve for my model. Thanks in advance, Manuel Morales
