Assess the accuracy of the log rank statistic approximation to the true value, in the case without censoring. Provides plots of statistics, and empirical test level.

Description

Assess the accuracy of the log rank statistic approximation to the true value, in the case without censoring. Provides plots of statistics, and empirical test level.
