projectionplotvariables(Y, X, W)

Arguments

• Y: The data. A m by n matrix, where m is the number of samples and n is the number of features.
• X: A m by p matrix containing the factor(s) of interest.
• W: A m by k matrix containing the estimated unwanted factors.

Details

Typically intended for internal use, and called after adjustment for known covariates (Z).

Returns

A list containing - byx: Regression coefficients from regressing Y on X.

• bwx: Regression coefficients from regressing W on X.

• projectionplotalpha: A reparameterization of alpha.

• projectionplotW: A reparameterization of W.
