Reliability Statistics:
According to Barker, Pistrang and Elliot (2010, p 62) reliability refers to the degree of reproduce ability measurement. A variety of different statistics are used to measure reliability. For some reason confusion continues to surround their use and selection. The first step is to set up which measurement scale is involved since this determines the reliability statistics. For practical needs only interval and nominal scales required to be assumed. Ordinary scales are analyzed as if they were interval scales. The methods used to quantify reliability are the statistics and probability mathematics. Reliability statistics can be widely categorized into the discrete functions treatment, point processes and continuous functions. Reliability is based on two state discrete systems since the component is in either in a failed or operational state. Continuous functions describe those situations which are ruled by a continuous variable such as distance or time travelled. The variations between continuous and discrete functions are one of how the problem is treated and not necessarily of the mechanics or physics of the situation. One of the most common reliability statistics is the reliability coefficient which is an index that takes on value from 0.0 to 1.0. A reliability coefficient of 0.0 denotes that the scores are wholly undependable whereas the 1.0 coefficient denotes that the scores are wholly dependable.

可靠性统计:

根据巴克,pistrang和埃利奥特(2010,p 62)的可靠性是指一定程度的繁殖能力的测量。各种不同的统计是用来测量的可靠性。由于某种原因,混乱继续包围他们的使用和选择。第一步是建立衡量尺度是因为这决定的可靠性统计。实际只需要间隔和名义尺度需假设。普通的尺度进行分析如果他们间隔尺度。运用定量分析的方法对可靠性进行概率统计数学。可靠性统计可分为离散函数处理,点过程和连续函数。可靠性是因为部件是在失败或运行状态对两种状态的离散系统的基础。连续函数描述这些情况是由一个连续变量,如距离或时间统治了。连续和离散函数之间的变化是一个问题如何处理,不一定是形势的力学和物理学。最常见的一种可靠性统计是一个指数,以从0到1的值的可靠性系数。0的可靠性系数表示的分数是完全不可靠而1系数表示的分数是完全可靠的。
