make.logtrans {CollocInfer}  R Documentation 
Functions to modify liklihood, transform, lik
and proc
objects so that the operate with the state defined on a log scale.
make.logtrans() make.exptrans() make.logstate.lik() make.exp.Cproc() make.exp.Dproc()
All functions require more
to specify the original object (ODE right hand side functions,
definitions of lik
and proc
objects).
A list of functions that calculate log transforms and derivatives in various contexts.
make.logtrans 
modifies the right hand side of a differential equation and its derivatives for a loged state vector. 
make.exptrans 
modfies a map from states to observations to a map from logged states to observations along with its derivatives. 
make.logstate.lik 
modifies a
