Correlation between two ordinal categorical variables Investigating inter-individual differences in short-term intra-individual variability. I would use rcorr with Pearson which has the advantage of also including p-values, but I am not sure if it qualifies for this sort of data. but we would say that it is an ordinal variable. Dynamic structural equation models with binary and ordinal outcomes in Mplus. Muthn & Muthn. Multiple imputation after 18+ years. NeuroImage, 65, 310319. intrinsic ordering to the categories. LISREL program and FACTOR software could do the polychoric correlation. The ordinal variable looks like it is actually 6 variables (one for each fruit). For example, using the hsb2 data file we can run a correlation between two continuous variables, read and write. For two discrete variables X and Y, the calculation is as follows: $$I(X;Y) = \sum_{y \in Y} \sum_{x \in X} correlation ordinal-data association-measure Share Cite Improve this question Follow I would like to calculate the correlation between the two vectors, to find whether there is some kind of relationship between the class of the zone and the winning candidate (i.e. What is this brick with a round back and a stud on the side used for? addition to being able to classify people into these three categories, you can order the It sounds like "accuracy" would depend on "preference".
