助田口方法里面的方差计算公式和效应分数在minitab中的设置
建立了一个3因素2水平的田口设计, 去找每个因素的所占的效应分数,
谢谢
田口的表和结果
A B C result
1 1 1 30
1 2 2 25
2 1 2 34
2 2 1 27
1______计算方差的公式不太明白。
看过论坛帖子http://www.6sq.net/article-30547.html
找到minitab的帮助文档,上传不了图片。。。。。
里面的公式是
SS (A)= nb
Si (yi..
-
y...)2
A1~=(30+25)/2=27.5(上划线,平均打不出)
A2~=(34+27)/2=30.5
A~=(27.5+30.5)/2=29
SeqSS(A)=nb((27.5-39)^2+(29-30.5)^2)=4.5n*b <>9
这个n 和b是怎么来的, 结果不等于软件里面的9???
应该的公式是怎么算的?
公式看不明白,请给出算a的过程就行了。
minitab 运行过程如下,
Taguchi Orthogonal Array Design
Source DF Seq SS Adj SS Adj MS F P
A 1 9.000 9.000 9.000 **
B 1 36.000 36.000 36.000 **
C 1 1.000 1.000 1.000 **
Error 0 *
Total 3 46.000
** Denominator of F-test is zero.
S = *
MANOVA for A cannot be done. Degrees of freedom for error is less than the
number of responses.
NOTE Could not graph the specified residual type because MSE = 0 or the
degrees of freedom for error = 0.
2_______效应分数问题,P没有计算,
怎么在软件里面选择这个项,怎么没有计算,来看每个因素对结果的影响百分比
p-value (P)Used in hypothesis tests to help you decide whether to reject or fail to reject a null hypothesis. The p-value is the probability of obtaining a test statistic that is at least as extreme as the actual calculated value, if the null hypothesis is true. A commonly used cut-off value for the p-value is 0.05. For example, if the calculated p-value of a test statistic is less than 0.05, you reject the null hypothesis.
