M-dependent stationary process

    [SOLVED] m-dependent stationary process

    Hi all

    Could you tell me a strict mathematical definition of "m-dependent stationary process" or maybe a link to where I could find it

    Thanks In Advance

    And may be you know what is the dependence between m-dependent stationary process (where m=q) and ARMA(0,q) process???

    Loosely, ARMA(0,q) = AR(0) + MA(q) = MA(q) which is [itex]X_t = \epsilon_t + \sum_{i=1}^m \theta_i \epsilon_{t-i}[/itex] (since q = m). See this link. You should be able to work out what this implies for m-dep. stat. process. (Hint: are Xt and Xs dependent or independent when t - s > m?)
