To compare two exponential distributions with or without censoring, two different statistics are often used; one is the F test proposed by C OX (1953) and the other is based on the efficient score procedure. In this paper, the relationship between these tests is investigated and it is shown that the efficient score test is a large‐sample approximation of the F test.
