fitted: Fitted Matrix in NMF Models

Description Usage Arguments Details Value Methods (by generic)

Description

Computes the estimated target matrix based on a given NMF model. The estimation depends on the underlying NMF model. For example in the standard model V ~ W H, the target matrix is estimated by the matrix product W H. In other models, the estimate may depend on extra parameters/matrix (cf. Non-smooth NMF in NMFns-class).

Usage

1
fitted(object, ...)

Arguments

object

an object that inherit from class NMF

...

extra arguments to allow extension

Details

This function is a S4 generic function imported from stats::fitted in the package stats. It is implemented as a pure virtual method for objects of class NMF, meaning that concrete NMF models must provide a definition for their corresponding class (i.e. sub-classes of class NMF). See NMF for more details.

Value

the target matrix estimate as fitted by the model object
