摘要
针对Matlab6.5统计工具箱没有优化正态总体方差的区间估计,且没有给出正态总体方差检验的问题,通过编写Matlab程序,优化统计工具箱对正态总体方差的区间估计,开发正态总体方差的假设检验算法.实例表明该方法在推断统计方面实用性较强.
The interval estimation on variance of normal distribution isn＇ t optimized in Matlab 6.5 statistics toolbox, and it doesn＇ t provide hypothesis testing on variance of normal distribution. So a Matlab program is developed to optimize interval estimation on variance of normal distribution and provide arithmetic of hypothesis testing on variance of normal distribution. The examples show that the method has better practicability on deducing statistics.
