Statistical interpretation of data - techniques of estimation and tests relating to means and variances of normal distributions 数据的统计处理和解释正态分布均值和方差的估计与检验方法
The results showed there were normal distribution patterns between each factors and it ' s frequency 结果表明:长穗苜蓿植株群体穗长、小花数、荚果数、种子数出现的频数均近似呈正态分布。
In chapter four , a simplified method of tailvar calculation is given under assumption of normal distribution 由于tailvar方法计算较为繁琐,论文会基于正态分布假设给出了一个简化方法。
The distributions of the values of fluctuating pressure conform to the law of normal distribution ; and the dominant frequency is low frequency 脉动压强幅值分布符合正态分布规律,优势频率为低频。
There are various quantities which need to be computed repeatedly in the analysis , and these are based on normal distribution functions 一些变量在分析中必须一遍遍的计算,这些都建立在正态分布的基础上。
