Phi and cramer's v
Did you know?
WebCramer's V must lie between 0 (reflecting complete independence) and 1.0 (indicating complete dependence or association) between the variables. If the number of rows or the number of columns in the conting ency table is two, the value of Cramer’s V is identical to the value of phi. C. Statistical (null) hypothesis (Chi-square test of ... WebThe p-value for Cramer's V and the Phi coefficient are based on chisq.test (). If any expected value of a table cell is smaller than 5, or smaller than 10 and the df is 1, then fisher.test () is used to compute the p-value, unless statistics = "fisher"; in this case, the use of fisher.test () is forced to compute the p-value.

Webperform a chi-square analysis [the logic and computational details of chi-square tests are described in Chapter 8 of Concepts and Applications];: calculate Cramer's V, which is a measure of the strength of association among the levels of the row and column variables [for a 2x2 table, Cramer's V is equal to the absolute value of the phi coefficient]; ... WebCramer's V statistic allows to understand correlation between two categorical features in one data set. So, it is your case. To calculate Cramers V statistic you need to calculate confusion matrix. So, solution steps are: 1. Filter data for a single metric 2. Calculate confusion matrix 3. Calculate Cramers V statistic
