AbstractA new statistic o/o(max) is introduced in this paper. If the proposed luminosity function correctly describes the distribution of the adopted sample, then the values of o/o(max) would be uniformly distributed in the interval [0, I]. We find that the o/o(max) test of the luminosity function is a necessary one, and the o/o(max) test is independent of the n/n(max) test which is a revision of the famous V/V-max test, presented in our previous work (Qin & Xie 1997). It is proved that two given distributions of o/o(max) and n/n(max) correspond to a unique normalized luminosity function. The distributions of o/o(max) and n/n(max) therefore provide a sufficient test for any adopted forms of the luminosity function. As a demonstration, we present a simple application of the method to a luminosity function and a sample found in the literature.
