Estimated parameters with 95% confidence intervals for the model of equation (3.6) for the rate of ISA infection of salmon farms. From left to right: (i) full model estimated on data from February 2003 to August 2009, (ii) gene effect ω set to 0, estimated on data from February 2003 to August 2009, and (iii) gene effect ω set to 0, estimated on data from February 2003 to 2007 as presented in Aldrin et al. [6]. The time delay is assumed to be six months. Gen. dist., genetic distance; CI, confidence interval; est., estimate; susc., susceptible; inf.; infectious.
