We have considered the decision problem facing an agent controlling a nonlinear regression process when parameters in the mean function and in the error distribution are unknown. The agent faces a tradeoff between accumulating information by varying the values of the regressors and accumulating one-period reward by following the one-period expected reward maximizing policy. We show that the problem can be brought into the dynamic programming framework and that the value function satisfies the usual functional equation. The sequence of beliefs about the unknown parameters is shown to converge almost surely. Further, the optimal action process converges to the one-period optimal action under limit beliefs.
