pmdc {EDMeasure} | R Documentation |
pmdc
measures conditional mean dependence of Y
given X
adjusting for the
dependence on Z
, where each contains one variable (univariate) or more variables (multivariate).
Only the U-centering approach is applied.
pmdc(X, Y, Z)
X |
A vector, matrix or data frame, where rows represent samples, and columns represent variables. |
Y |
A vector, matrix or data frame, where rows represent samples, and columns represent variables. |
Z |
A vector, matrix or data frame, where rows represent samples, and columns represent variables. |
pmdc
returns the squared partial martingale difference correlation
of Y
given X
adjusting for the dependence on Z
.

# X, Y, Z are 10 x 2 matrices with 10 samples and 2 variables X <- matrix(rnorm(10 * 2), 10, 2) Y <- matrix(rnorm(10 * 2), 10, 2) Z <- matrix(rnorm(10 * 2), 10, 2) pmdc(X, Y, Z)
