Given a Gaussian process X(t), identify which of the following , if any, are gaussian processes. (a)X(2t) solution said that X(2t) is not gaussian process, since and similarly Given Poisson process X(t) (a) X(2t) soultion said that X(2t) is not poisson process, since same reason above. BUT I think that in stochastic process, Time t is just constant value. so I think X(2t), X(10000t), X(t+100) is also gaussian process ,or poisson process doesn't care about whatever t is. answer is?
