Hi Everyone,
Im seeking if anyone can give me the e-mail address of RICC Francis. My problem is this: I have been looking at his (1988) paper comparison of tagging and age based data and particularly on the re-parameterisation of the VBGF (equation 4 on his paper). What i find is that `r' always comes to 1, making the terms (1-r) coming to zero and hence the whole product as zero. This makes the calculation of expected length at an arbitrat age coming to be similar to Lo. I would appreciate any help from anyone on the list.
cheers
