computeCoefficients: Compute coefficients

Description Usage Arguments Value Author(s) Examples

Description

Compute coefficients at a given level of penalty

Usage

1
computeCoefficients(x, lambda, mode = "fraction")

Arguments

x

a LarsParth object

lambda

If mode ="norm", lambda represents the l1-norm of the coefficients with which we want to predict. If mode="fraction", lambda represents the ratio (l1-norm of the coefficientswith which we want to predict)/(l1-norm maximal of the LarsPath object).

mode

"fraction" or "norm" or "lambda".

Value

A list containing

variable

Index of non-zeros coefficients.

coefficient

non-zeros coefficients.
