Correlation for quadratic relationship

Hi everyone,

Does anyone of you know if it's possible to test for a quadratic (instead of linear) relationship in JASP? I only have two variables I want to correlate this way. Oh, I'd like to get Bayes Factors for this quadratic correlation. Thanks in advance!

  • Hi Kevin,

    Well, we don't have that in there just yet (although I like the idea of having a measure of association that is very general) but I guess most people would use linear regression and use polynomial predictors...so include both x, x^2 as predictors (https://en.wikipedia.org/wiki/Polynomial_regression)
