Transform PARAFAC loadings to an orthonormal basis. Note: this function only works for 3-way PARAFAC models.

Transform PARAFAC loadings to an orthonormal basis. Note: this function only works for 3-way PARAFAC models.

Usage

transformPARAFACloadings(Fac, modeToCorrect, moreOutput = FALSE)

Arguments

Fac

Fac object from a PARAFAC object, see parafac().

modeToCorrect

Correct the subject (1), feature (2) or time mode (3).

moreOutput

Give orthonormal basis and transformation matrices as part of output (default FALSE).

Value

Corrected loadings of the specified mode.

Examples

processedFujita = processDataCube(Fujita2023, sparsityThreshold=0.99, centerMode=1, scaleMode=2)
model = parafac(processedFujita$data, nfac=2, nstart=1, verbose=FALSE)
transformedA = transformPARAFACloadings(model$Fac, 1)
#> Error in Fac[[1]]: subscript out of bounds
