Yes thank you, as far as I understood your proposal it would lead to a similar result. Is there a good package in order to do principal component analysis?

Consider using principal components on the log-differences of your yield-curve time series. That sort of gives you something like latent variables. You'll get a bunch of stationary random processes together with factor loadings for your maturities. You can then draw MC-samples from these processes to simulate future yield curves ... if that is indeed what you are after ...

In fact, I am looking for a package where I as input several given vector variables which are part of an autoregressive model. Then I would like to obtan parameters for so called latent variables.
