Ordinal Synchronization: Using ordinal patterns to capture interdependencies between time series

open access: yes, 2018
We introduce Ordinal Synchronization ($OS$) as a new measure to quantify synchronization between dynamical systems. $OS$ is calculated from the extraction of the ordinal patterns related to two time series, their transformation into $D$-dimensional ...

Quantifying association in ordinal data [PDF]

open access: yesJournal of Family Planning and Reproductive Health Care, 2010
What is non-parametric correlation? A non-parametric (or ordinal) correlation coefficient for two variables quantifies the extent to which there is, in the study sample, a consistent relationship between the values for the two variables. The correlation coefficient indexes the strength of the relationship found, from zero (no discernible relationship ...
