I've graphed the data for the two variables (see picture below) and it seems that they have a non-monotonic relationship. I'm not sure what test to use since they. Statistics Definitions > Monotonic Relationship What is a Monotonic If your variables are monotonic and linear, a more appropriate test might.
monoRelation implements the 'monotonic relationship' tests from Patton & Timmermann (, JFE).

Thank you in advance. Statistical data preparation: management of missing values and outliers.
Maybe Pearson correlation for real-valued variables and maybe chi-squared for categorical variables. Tweet to rdrrHQ. It can be used for both continuous and discrete ordinal variables, and can be calculated as:.

Detect NonLinear and Non Monotonic Relationship between Variables
Spearman's correlation is a non-parametric measure of rank correlation between two variables, it assesses the monotonic relationship (weather. function is. A monotonic function is one that either never increases or never decreases monotonic relationship between paired data. In a sample it is However, we need to perform a significance test to decide whether based upon this.
Perhaps SVM, probably not random forest.
It can be used for ordinal variables. It is sensitive to outliers.
Reinstate Monica. The chi-square test statistic is calculated as:.
