Abstract:

Air environmental spectrum is the important composing part of airplane service environmental spectrum. Large amount of spectrum data without evident dividing line is classified by fuzzy clustering method. The homogeneity between their parent distribution functions is tested by three commonly used hypothesis testing methods: t distribution hypothesis test, rank-sum test and Smirnov test.
