You need to load the package DiscreteMath`RSolve. You can then use the command RSolve, which looks a lot like DSolve (for differential equations). Then try: RSolve[y[t] == a + b y[t - 1] + y[t - 2], y[t], t] "Wilfried Stock" <stock at wirtschaft.uni-kassel.de> wrote in message news:8k3l8a$3af at smc.vnet.net... > > Hi > I would like to built a difference equatition like: > Yt=A+b*Yt-1-c*Yt-2 > with Y=f(X) > I don't find an easy solution. > Can anyone provide a solution? > > > Thanks in advance, > Wilfried >
