if i have xt = 1.004 * xt-1 + ut
and yt = 1.04 * yt-1 + vt

where ut and vt are normally distributed white noise processes with mean = 0 and standard deviation = 0.01

how do i enter these in stata? and how do I see if x and y are stationary/non-stationary?

i am completely new to stata, please help me out, i am trying to better myself at equations and graphs in stata

thank u!
