If a Levy process admits exponential moments, then there exists a parametricįamily of measure changes called Esscher transformations.

These keywords were added by machine and not by the authors. This process is continued until either the first or the second decision is made.
#Sequential testing of levy process trial
Again on the basis of the first two trials one of the three decisions is made and if the third decision is reached a third trial is performed, etc. If the third decision is made, a second trial is performed. If the first or the second decision is made, the process is terminated. On the basis of the first trial, one of the three decisions mentioned above is made.
Thus, such a test procedure is carried out sequentially. By a sequential test of a statistical hypothesis is meant any statistical test procedure which gives a specific rule, at any stage of the experiment (at the n-th trial for each integral value of n), for making one of the following three decisions: (1) to accept the hypothesis being tested (null hypothesis), (2) to reject the null hypothesis, (3) to continue the experiment by making an additional observation.
