We study a q-voter model with stochastic driving on a complete graph with q being a random variable described by probability density function P(q), instead of a constant value. We investigate two types of P(q): (1) artificial with the fixed expected value 〈q〉, but a changing variance and (2) empirical of freely forming groups in informal places. We investigate also two types of stochasticity that can be interpreted as different kinds of nonconformity (anticonformity or independence) to answer the question about differences observed at the macroscopic level between these two types of nonconformity in real social systems. Moreover, we ask the question if the behavior of a system depends on the average value of the group size q or rather on probability distribution function P(q).
我们研究了一个在完全图上具有随机驱动的 q-投票者模型，其中 q 是由概率密度函数 P(q)描述的随机变量，而不是一个常数。我们研究了两种类型的 P(q)：(1) 具有固定平均值〈q〉但方差变化的人工，(2) 在非正式场所自由形成群体的经验。我们还研究了两种类型的随机性，可以将其解释为对回答在真实社会系统中这两种类型的非一致性在宏观水平上观察到的差异的不同类型的不服从（反服从或独立性）。此外，我们还询问了系统的行为是否取决于群体大小 q 的平均值，还是取决于概率分布函数 P(q)。
