Partial correlation quantifies the linear relationship between two variables while controlling for the effect of one or more additional variables. It isolates the direct association between the pair by removing shared variance attributable to the conditioning variables, computed as the correlation of residuals from separate regressions of each variable on the controls, or equivalently from the inverse covariance matrix. It persists through statistical software implementations, econometric practice, and scientific methodology textbooks.

Definition
Why it is in scope
A human-made statistical measure that quantifies the linear relationship between two variables while controlling for the effect of one or more additional variables. It is constructed through regression-based residualization or inverse covariance computation, and persists through statistical software packages, econometric practice, and scientific methodology.

Tested INSTANCE_OF: partial correlation IS a specific kind of statistical method. It is a defined procedure for measuring association between variables while controlling for confounds — a competent speaker would call it 'a statistical method.' Nearest kind: statistical method (not regression, which is a tool used within it).
- cmrw5yp7v001nkyo64adfdvitDERIVED_FROM →
Tested which-came-first: plain correlation predates partial correlation historically. Pearson developed correlation (r) in the 1890s and partial correlation in 1900. Correlation is the original measure; partial correlation is the controlled extension that removes confounding variance. Y (correlation) existed first and fed into X (partial correlation).
