For Example 1 ofChi-square Test for Normality, SHAPIRO(A4:A15, FALSE) = .874 and SWTEST(A4:A15, FALSE, FALSE) = SWPROB(15,.874,FALSE,FALSE) = .0419 (referring to the worksheet in Figure 2 ofChi-square Test for Normality). Note that SHAPIRO(R1, TRUE), SWTEST(R1, TRUE), SWCoe...
AI检测代码解析 # 生成100个服从正态分布的随机数data<-rnorm(100)# 进行Shapiro-Wilk正态性检验result<-shapiro.test(data)# 打印检验结果print(result) 1. 2. 3. 4. 5. 6. 7. 8. 上述代码中,我们使用rnorm()函数生成了100个服从正态分布的随机数,并存储在名为data的变量中。然后,我们使用shapiro.tes...
Shapiro-Wilk Test in Google Sheets Shapiro-Wilk test can be conducted in Google Sheets in a similar way as done in Excel as shown in the picture below.
Este tutorial mostrará cómo realizar el Test de Shapiro-Wilk en Excel y Google Sheets. ElTest de Shapiro-Wilkes un test estadístico que se realiza para determinar si un conjunto de datos puede modelarse mediante la distribución normal y, por tanto, si puede decirse que un subconjunto d...
1. A formal normality test:Shapiro-Wilk test. This is one of the most powerful normality tests. 2. Graphical methods:QQ-Plot chartandHistogram. The Shapiro Wilk test uses only theright-tailedtest. When performing the test, the W statistic is only positive and represents the difference between...
R:Although not as popular as SPSS or Excel, R does have the ability to perform the test. The argument is very simple: > shapiro.test(sample) You can find more information about the argumenthere. Excel:This articlehas a very good outline of how to run the test in Excel for samples up...
步骤一：准备数据 我们需要准备一组数据，这组数据可以是任何服从某种分布的数据。在Matlab中，我们可以将这组数据存储在一个数组中，例如：data = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10];步骤二：调用Shapiro-Wilk函数 Matlab提供了用于执行Shapiro-Wilk正态检验的函数，这个函数叫做swtest。我们可以直接调用...
