Let {X"k,k@?Z} be a zero mean causal AR(~) process with parameter @Q@?R^~. A very common fitting procedure is to employ the Yule-Walker equations in connection with the Durbin-Levinson algorithm, which yields the (recursive) sequence of estimators @Q@^"m:=(@q@^"m","1,...,@q@^"m","m)^@?, m=1,2,..... Under mild conditions, simultaneous confidence bands for @Q@^"m, @Q@^"m"+"1,... are derived. More precisely, it is shown that max"d"""n"-"@k"""n"@?"m"@?"d"""nmax"1"@?"h"@?"m|@q@^"m","h-@q"h| converges to an extreme value distribution, where d"n=O(n^@d), @d0, and n denotes the sample size. The relation of @k"n and d"n depends on the bias term @?"i"="d"""n"-"2"@k"""n^~|@q"i|. This significantly extends a recent result in Jirak (2012). Moreover, extensions of results of An et al. (1982) and Bhansali (1978) are obtained. In addition, the behavior of Information criteria in the AR(~) setting is briefly discussed.
