multiway (version 1.0-2)

rescale: Rescales Multi-Way Factors

Description

Rescales factors from a multiway object.

Usage

"rescale"(x, mode="B", newscale=1, ...)
"rescale"(x, mode="A", newscale=1, absorb="C", ...)
"rescale"(x, mode="A", newscale=1, absorb="C", ...)
"rescale"(x, mode="B", newscale=1, ...)
"rescale"(x, mode="A", newscale=1, ...)

Arguments

x

Object of class "indscal" (output from indscal), class "parafac" (output from parafac), class "parafac2" (output from parafac2), class "sca" (output from sca), or class "tucker" (output from tucker).

mode

Character indicating which mode to rescale.

newscale

Desired mean-square for each column of rescaled mode. Can input a scalar or a vector with length equal to the number of factors for the given mode.

absorb

Character indicating which mode should absorb the inverse of the rescalings applied to mode (cannot be equal to mode).

...

Ignored.

Value

Same as input.

Details

See indscal, parafac, parafac2, sca, and tucker for more details.
