There's an extension to the package nlme using odesolve to estimate parameters of models defined by ODEs. It's called nlmeODE and has a home page here: ; it's on CRAN

Dear list,

I have a degradation model:

dX/dt = * I(X2)*( k1*X(t) )/( X(t)+k2 )

where X(t) is concentration at time t, and k1 and k2 are parameters that I want to estimate. I(X) is a known inhibitor function.

My questions is whether this is implemented or easily computed in any R package. I have searched the archives but without luck.

Any help or comments on this would be appreciated, Klaus Andersen mailing list PLEASE do read the posting guide! mailing list PLEASE do read the posting guide! Received on Sat May 21 01:13:35 2005
