What are the assumptions associated with the chi-square test for multi-way tables?

Dec 28, 2023 ... If the explanation is that for 2 alleles there is 1 "free" parameter to vary because if you know p or q you can derive the other as 1-p or 1-q, ... The chi-square test is a statistical method commonly used in data analysis to determine if there is a significant association between two categorical variables. The Chi-Square Test is a statistical test used to determine whether there is a significant difference between observed and expected frequencies in a categorical ... 6 The Chi-Square Test · > x=rnorm(10000,0,2) > y=rnorm(10000,0,2) > z=rnorm(10000,0,2) > w=rnorm(10000,0,2) · > hist(x, breaks=100, freq=F) · > x2=x^2 > hist(x2, ...
