Before revision: We are introducing the new family of the Continuous Time Random Walks (CTRW) with long-term memory within consecutive waiting times.
After revision: In many physical, social or economical phenomena we observe changes of a studied quantity only in discrete, irregularly distributed points in time. The stochastic process used by physicists to describe this kind of variables is the Continuous Time Random Walks (CTRW) with long-term memory within consecutive waiting times.
