In summary, we discussed the relationship between stationary increments and time homogeneity in a counting process. It is true that if a counting process has stationary increments, then it is time homogeneous. Similarly, independent increments also give rise to the Markovian property. However, the opposite implications are false. Additionally, there is a connection between stationary increments and the Markovian property, as demonstrated by the nonhomogeneous Poisson process. It is not accurate to say that Markovian property implies stationary increments, but it is possible for the opposite implication to hold.

Hello

Is it true that if a counting process has stationary increments, then it is time homogeneous?
stationary increments → time homogeneous?

And is it also true that independent increments gives Markovian property?

that is :
independent increments → markovian property ?

The opposite implications are false?

And is there a connection between stationary increments and the markovian property? I know that the nonhomogeneous poisson process is a markov process. So we can not say that markov → stationary increments, but can the opposite implication hold?

I'm sorry you are not generating any responses at the moment. Is there any additional information you can share with us? Any new findings?
 

1. Is the Markov property always true for stationary increments?

No, the Markov property is not always true for stationary increments. It is only true for certain types of processes, such as Markov processes or stationary stochastic processes.

2. What is the difference between stationary increments and the Markov property?

Stationary increments refer to the behavior of a stochastic process, where the difference between two time intervals is independent of the starting time. The Markov property, on the other hand, refers to the future behavior of a process being independent of the past behavior given the present state.

3. Can a process have stationary increments but not satisfy the Markov property?

Yes, it is possible for a process to have stationary increments but not satisfy the Markov property. This could occur if the process has certain memory-dependent behaviors that violate the Markov property.

4. How do you determine if a process has stationary increments?

To determine if a process has stationary increments, you can plot the difference between two time intervals and see if it follows a consistent pattern over time. If the differences are independent of the starting time, then the process has stationary increments.

5. Are stationary increments and the Markov property related?

Yes, stationary increments and the Markov property are related in that a process with stationary increments is more likely to satisfy the Markov property. However, it is not a guarantee and depends on the specific behavior of the process.
