What is a stationary time series process? correct answers One whose probability distributions are stable over time - if we take any collection of random variables in the sequence and then shift that sequence ahead by h time periods, the joint probability remains unchanged When is a stochastic process stationary? correct answers a stochastic process is stationary if for every collection of indices is greater than 1 and the previous time period, the joint distribution of the x values is the sam...
