lsoda warning "too much accuracy requested"
Dear list -
Does anyone have any ideas / comments about why I am receiving the following
warning when I run lsoda:
1: lsoda-- at t (=r1), too much accuracy requested in: lsoda(start, times,
model, parms)
2: for precision of machine.. see tolsf (=r2) in: lsoda(start, times,
model, parms)
I have tried changing both rtol and atol but without success. I saw the
thread in the R-archive of 11 June 2004 but this has not helped me.
I have built the model in stages and the problem only occurs when the
exponent beta in the third DE is any...
