Package: ef Title: Modelling Framework for the Estimation of Salmonid Abundance Version: 2.0.0 Date: 2026-10-09 Authors@R: c( person("Colin", "Millar", role = c("aut", "cre"), email = "colin.millar@ices.dk"), person("Rob", "Fryer", role = "aut"), person("Iain", "Malcolm", role = "aut"), person("Ross", "Glover", role = "aut"), person("Marine Scotland Science", role = "cph")) Description: Estimates capture probabilities and densities from multipass removal (electrofishing) data, following Millar et al. (2016) . Capture probability is modelled on the logit scale using fixed effects, penalised smooth terms and random effects, for example for between visit and between sample variation. The likelihood is computed using 'RTMB', with random effects integrated out using the Laplace approximation.
