2、The sample breakdown point of a test for moment estimation of population variance;

4、The calculation formulas of sample size based on the error limitation are given for estimation of population mean.

6、In this paper, two methods of maximum likelihood estimation of population unknown parameters in the case of one-dimensional fuzzy random variables are studied, i. e. the extension principle method and the integrable selection method of random sets.

1、estimation of population variance

5、This paper deals with the estimation of population mean in systematic sampling by use of auxiliary information in order to improve the accuracy of the estimate.

3、To forecast the outbreak of pest insects is based on the estimation of population density.

7、In this paper, We give the sample breakdown point of a test for moment estimation of population variance and analyze the asymptotically normal characteristic of the sample breakdown point.
