Investigating inter-individual differences in short-term intra-individual variability. Accessed 31 Mar 2023. Can I still talk of correlations in this case or do I need to talk about significance of association? If I use hetcor I seem to gain the advantage of it being applicable for categorical data, but I don't get the p-values. Spearman correlation requires the variables be at least ordinal in nature. distribution of the individual observations from the sample to be normal. If you want to take a different approach, you could get complex and look at a multilevel model, with subject being repeated. Connect and share knowledge within a single location that is structured and easy to search. Thanks for your clarification.

(Assuming the method can handle ties well for ordinal data). sample means are normally distributed. There are three metrics that are commonly used to calculate the correlation between categorical variables: 1. A random walk algorithm suggested by Chib and Greenberg (1998) can support arbitrary covariance structures and can be implemented in Mplus by specifying ALGORITHM=GIBBS(RW). Rather than integrating over a sum or summing over an integral, I imagine it would be easier to convert one of the variables into the other type.

A prescription is presented for a new and practical correlation coefficient, K, based on several refinements to Pearson's hypothesis test of independence of two variables.The combined features of K form an advantage over existing coefficients. (because the spacing between categories one and two is bigger than categories two and 855885). These can be used to test whether two variables you want to use in (for example) a multiple regression test are autocorrelated. Structural Equation Modeling, 28(1), 1527. but we would say that it is an ordinal variable. But how high an MI is corresponding to the corr=1 and how low an MI corresponds to corr=0? Is this correct?
