Generalised estimating equations (GEE, normal distribution, identity link function, autocorrelation structure between observation periods) for the influence of IG predator species (no, low, or high risk for IG prey; low or high risk for IG predator) on time, distance and path shape parameters of the IG prey Neoseiulus californicus and IG predators Phytoseiulus persimilis (low risk) and Amblyseius andersoni (high risk) over time (three observation periods: 0–5, 5–10, 10–15 min)
