Test Martingales for bounded random variables

Hendriks, Harrie

Understand

Given a random sample from a random variable $T$ which is bounded from above, $T\le\tau$ a.s., we define processes that are positive supermartingales if $E(T)\ge\mu$.

  • Such processes are called test martingales.
  • Tests of the supermartingale hypothesis implicitly test the hypothesis $H_0:E(T)\ge\mu$.
  • We construct test martingales that lead to tests with power 1.
