The result showed that the flora has more association with the South China and East China. The endemic type of China wa 21.74%,the east Asia & north disjuncted America distribution type was 17.38% and the East Asia one 13.04%,North temperate one 13.04% at generic level,and the temperate elements are slightly more than the tropical ones(11∶7).
A male distribution type, however, was not produced by it.
The histograms of the distribution in normal and regenerative glands were a normal type and subnormal type, respectively, while adenocarcinoma showed an abnormal distribution type.
For a time series with normal, exponential, Pearson 3, EV1 (Gumbel), or generalized Pareto (GP) distribution type, the null distribution of its rk can be approximated by the normal distribution with mean -1/(n-k) and variance 1/(n-1).
But for a time series with the lognormal, EV2 or EV3 (Weibull) distribution type, the null distribution of rk is skewed distributed.
It has been considered that the test is more suitable for non-normally distributed data and it may be not sensitive to the distribution type of sample data.
