Table 1 Model parameters
From: The weakness of weak ties for novel information diffusion
Parameter | Definition | Set to |
|---|---|---|
x | Number of network neighbors a newly-informed node encounters in a period | 2 |
p strong | Probability pass news to an encountered neighbor if neighbor is same type | 1 |
p weak | Probability pass news to an encountered neighbor if neighbor is different type | {.25,.5} |
τ={τ 1,…,τ n} | Set of types | {τ 1,τ 2}, |
\(q^{\tau ^{k}}\) | Proportion of type τ k∈τ={τ 1,…,τ n} present in the network | \(\frac {1}{2}\) |
Homophily | Prop. same-type ties in network minus prop. same-type ties expected under random tie formation | {0,.15,.3,.45} |
Diversity | Number of types, or “groups,” present in network | 2 |
