It is well-known that the presence of a herding mechanism in the model is not sucient for non-Gaussian properties, which …

Stock markets can be characterized by fat tails in the volatility distribution, clustering of volatilities and slow … Lux–Marchesi model have been used. We show that a simple herding model with only four parameters leads to a quantitative … description of the data. As a new type of data we describe the volatility cluster by the waiting time distribution, which can be …
