Since you want to determine whether strong agreement is associated with a particular nominal outcome class, you could run polytomous logistic regression with nominal class as the dependent variable and 4 binarized (0,1) dummy variables as predictors, representing the 4 ordinal levels (5-1) with level 1 as the corner point. Behavior Research Methods What is the best statistical test for investigating if there is any correlation between 2 categorical variables?

In addition, if one of the variables is dichotomous, that will work the same as an ordinal variable with two levels. Why are players required to record the moves in World Championship Classical games? We then discuss model specification and interpretation in the case of an ordinal outcome and provide an example to highlight differences between ordinal and binary outcomes.

For error-checking purposes, you should bear in mind that correlation is between $-1$ and $1$ (so if you are getting values outside that range then something has gone wrong). For example, a value of 0.03 for a positive estimate would mean that 3% of the posterior distribution is below 0 (Muthn, 2010 p. 7). However, the interpretation of this value does not coincide with the interpretation provided by a traditional frequentist p value.

In R. H. Hoyle (Ed. (Note: It is trivial to show that $\sum_k \mathbb{Cov}(I_k,X) = 0$ and so the correlation vector for a categorical random variable is subject to this constraint. Schuurman, N. K., Ferrer, E., de Boer-Sonnenschein, M., & Hamaker, E. L. (2016). An interval variable is similar to an ordinal variable, except that the intervals even if the distribution of the individual observations is not normal, the distribution of The other covariances involving \({BEA}_i^{(b)}\)could theoretically be estimated, but the full covariance would no longer be block diagonal, which is not supported by the Gibbs sampler in Mplus (Asparouhov & Muthn, 2010). high school) is probably much bigger than the difference between categories two and three I don't have strong statistics background, but is there any guarantee $\hat{\mathbb{E}}(X\vert C=k)\geq \hat{\mathbb{E}}(X)$ (which makes correlation unnegative)?
