Two exercises. Exponential and Cauchy's distributions. $\arctan (1/t) = \pi/2 - \arctan (t)$ I think... (at least for $0 \leq t\leq \pi/2$) draw a traingle to convince yourself. |

Does the sequence converge? ah **** why did I think it was right when i first wrote it down? :S |

Show that $Z_n = \frac{\sum_{i=1}^nX_i - n\mu }{\sigma \sqrt{n}}$ is equal to $\sum_{i=1}^n \frac{X_i - \mu} { \sigma \sqrt{n}}$ edited tags |

Does the sequence converge? +1 probably a better solution than mine :P (though 10 bucks says he doesn't know that limit) |

Question about Markov chain derived from a Poisson process you will not succeed finding the stationary distribution, because I think this is null recurrent. this is really a weird way of phrasing this question because $N_t-\lambda t$ is what you call a compensated Poisson process. |

Differences between a Markov jump process and a continuous-time discrete-state Markov process? not necessarily. Poisson processes and the continuous time discrete space processes are jump processes I would say. Generally, the ones people use for financial modelling (mentioned in one of your links, as extensions of Black scholes) tend to have continuous space. |
