I would like to do a chi-squared test on the following matrix:
CP<-
matrix
(c
(26,17,9,27,8,9,9,8,29,9,6,17,81,7,43,36,2,4,3,0,5,1,0,12,29,9,12,19,0,0
),nrow=3)
dimnames(CP) <-
list
(c
("less10
","bt10and50
","more50"),c("T10","T9","T8","T7","T6","T5","T4","T3","T2","T1"))
I want to set the expected values as 26, 17, 9 (ie. the data from
T10).
How do assign expected values and complete the Chi-squared test?
You ought to look (more closely?) at the examples in chisq.test.
