制作Cumulative Frequency Chart [Probability] 这里简单介绍一下如何创建 Probability Chart, 关键在于如何定位每个数据元在Y轴的位置, 应为Y轴是非线性分布的,这里肯定有一个非线性函数,它就是 Excel中的NormSinv() 如果手上有一组数据 [List /Array], 需要创建对应的Probability Ch
我们常用的统计分布图形有直方图(Histogram),趋势图(Trend Chart),箱图(Box Plot),Probability Chart (Cumulative Frequency Chart)。这些图形都是用来显示数据的统计分布的,其中直方图是最简单的;趋势图主要是用来显示数据随着事件的变化;箱图是在另一个维度的分布,同时加入了置信区间等信息;最近接触了Probability Cha....
For example, we would make a bar chart with two bars to show the number of men and women in a population. Let’s do a simple example for a histogram: The NEW ENERGY COMPANY makes pressurized heat pipes to sell commercially. The product performs well but there is concern that the ...
Probability Density Function(PDF) and its Application: In Statistics,Probability Density Function(PDF), a capacity whose integral is determined to discover probabilities related with a persistent random variable. Its chart is a bend ...
Determine (a) by using the chart (b) by using direct integration, the centroid of the area shown Locate the centroid of the shaded area. Express your answer in terms of some or all of the variables a and L. The function f(x)=e^-x can be use...
The probability density function of Xnis f(x)={n for 0≤x≤1n0 otherwise. . Let us now calculate the mean of the sequence of random variables {Xn}n≥1 mn=E[Xn]=∫ 01/nxf(x)dx=∫ 01/nxn dx=n∫ 01/nxdx=nx22|x=1/n=12n→n→∞0. The moment of order s...

On the basis of a medical chart, study participants were asked to judge which of two diseases their (hypothetical) patients were suffering from. The a priori probability of one of the diseases was three times higher than that of the other. The conditional probabilities were then varied by the...
As I mentioned, I really like probability distribution plots because they make distribution properties crystal clear. In the example above, we used the normal distribution. Because that distribution is so well-known, you might have guessed the general appearance of the chart. Now, let’s look at...
This interactive graphic presents 76 common univariate distributions and gives details on (a) various features of the distribution such as the functional form of the probability density function and cumulative distribution function, graphs of the probability density function for various parameter settings,...
