For example, i = 0,1,2, 00. M while i = 0,1 might denote two states, a claim has occurred or not etc... When we construct a Markov chain, it is possible to switch from one state to another with a given probability. This transition, from one state to another express the random character of the process.

The number of ways to operate is practically limitless, there are therefore many trading strategies fmancial managers and insurers can adopt to protect their wealth or to make money.
It is also possible to study a process volatility in terms of the range process of the time series, (Le. the mathematical process of the highest less the smallest value a series assumes over time) and potentially combine range statistics with standard deviation statistics, leading to an R/S analysis. These ideas are important for a number of reasons and will be considered in greater detail in Chapter 5 as well. Examples of volatility studies are numerous and express the attempt to "capture" nonlinear facets of a process stochastic behavior.
