WebThe basic idea behind the test is to compare the observed values in your data to the expected values that you would see if the null hypothesis is true. There are two commonly used Chi-square tests: the Chi-square goodness of fit test and the Chi-square test of independence. Both tests involve variables that divide your data into categories. WebGene-expression data often have a small number of samples; this presents a challenge to the chi-square test. A chi-square test needs 80% of elements of the expected frequencies bigger than 5, and this approximation breaks down if expected frequencies are too low . To meet this characteristic of gene-expression data, we propose a recursive ...
