On AR(1) processes with exponential white noise. (English) Zbl 0639.62082

Summary: We consider the autoregressive model \(X_ t=bX_{t-1}+Y_ t\) where \(0\leq b<1\) and \(Y_ t\) are independent random variables with an exponential distribution. The moments of the stationary distribution of \(X_ t\) are calculated and the distribution of an approximation to the maximum likelihood estimator for b is derived. The result is used for a construction of a confidence interval for b.
