Comparison of the Mean Time Between Failures for Two Systems Under Short Tests

Comparison of the Mean Time Between Failures for Two Systems Under Short Tests

A sequential probability ratio test (SPRT) is discussed, for comparison of two systems, one "basic" (b), and the other "new" (n), with exponentially distributed times between failures (TBF). The hypothesis that the mean TBF n /MTBF b ges 1 is checked, versus one that it is
