...I want to do an homogeneity test on seed colour segregation. I have
green and yellow seed in an a priori expected segregation ration of 3:1.
green<-c(85,130,110,107,70,45,30)
yellow<-c(26,41,51,35,36,16,11)
chisq.test(rbind(green,yellow))
Pearson's Chi-squared test
data: rbind(verdi, gialli)
X-squared = 6.2672, df = 6, p-value = 0.3939
That's fine. Now I want to tell chisq.test that I have my a priori expected
frequncies:
prob.green<-rep(3/4,7)
prob.yellow<-rep(1/4,7)
chisq.test(rbind(green,yellow), p=rbind(prob.green,prob.yellow))
Pearson's Chi-squared test
