The purpose of this study is to analyse the properties of these models with the help of computer simulations and, as a consequence, to explore some of their different fields of application. As a result, it can be observed that these processes, based on a stochastic geometry, can lead not ...
Stochastic Processes A stochastic process {Xt , t ∈ T} is a sequence of random variables (when T is discrete, e.g. T={ 0, 1, 2, …}) a “random function” (when T is continuous, e.g. T=[0,∞)) Index set T often represents time Xt is a discrete or a continuous random v...

Hence, such explanations cover the four stochastic principles of order relevant/with replacement, order relevant/without replacement, order irrelevant/with replacement, and order irrelevant/without replacement (see Berthold & Renkl, 2009; Schalk et al., 2020). In terms of models of cognitive skill ...
