Table 2 Models of (log) risk attitude as a function of games, participants and time

From: Spontaneous social distancing in response to a simulated epidemic: a virtual experiment

Model Formula Population μ Participants λ i Games ηi,k Time εi,k,t AIC
A log(αi,k,t) = μ + λ i  + ηi,k + εi,k,t –1.934 0.7354 0.2730 0.5833 14502
B log(αi,k,t) = μ + λ i  + εi,k,t –2.004 0.7935   0.6719 15835
C log(αi,k,t) = μ + η k  + εi,k,t –2.382   0.1697 0.9544 20235
D log(αi,k,t) = μ + εi,k,t –2.325    0.9628 20348
  1. Random effects (λ i , ηi,k) and time variability (εi,k,t) are distributed according to a normal distribution with average 0 and standard deviation listed in the table. AIC is the Akaike Information Criterion [40]
