| Abstract: | This paper analyzes the data from Mount Mogan by means of 7 kinds of methods. All indices show that the larvae are of aggregation patterns. This paper discusses briefly the application of the results in data transformation, determination of the best sampling numbers and sequential analysis, too. |
