| Abstract: | The paper deals with the determination on methods of the spatial distribution patterns of insects by means of an electronic computer. Newton-iteration method was adopted to estimate the value of K in Negative binomial distribution for the first time and different estimation methods of the K-value were analysed and made comparison in this paper. The results are as follows: Electronic computer not only is suitable for the determination of the distribution patterns, but also has the advantages of speed in calculating and accuracy. Newton iteration method is superior to linear interpolation method in the comparison of methods of estimation in the K-value and can accurately estimate the K-value. |
