Zero Order vs (Semi) Partial Correlation Test and Confidence Interval

  • Dan Richard MacEwan University


A bootstrap test was created to measure the significance of a partial or semi-partial correlation equaling its zero order correlation. This was implemented in R and accepted by CRAN as an open source package named zeroEQpart, which can be accessed by external researchers. In addition to a hypothesis test, the functionality of the R package was extended to include confidence intervals for the parameter (zero order minus partial). The test was administered retrospectively on an honours psychology thesis to analyze the effect of metacognitions on chronic pain and health anxiety.
