Abstract: Abstract. This study considers a time‐series model with random coefficients in cointegration. The estimation problem can be solved by maximizing the log‐likelihood. Asymptotic distributions of the least squares and maximum likelihood estimates are considered. The randomness of the cointegration vector is checked by a score‐based test approach. The test statistic converges asymptotically to a functional of Brownian processes. An empirical application to two cointegrated series, federal fund rate and 90‐day treasury bill rate is considered.
