trans_normal: Transform the marginals of a multivariate data set to standard normality based on the logspline density estimator (Kooperberg and Stone, 1991). See Otneim and Tj<U+00F8>stheim (2017) for details.

Description

Transform the marginals of a multivariate data set to standard normality based on the logspline density estimator (Kooperberg and Stone, 1991). See Otneim and Tj<U+00F8>stheim (2017) for details.

Usage

trans_normal(x)

Arguments

x

The data matrix, one row per observation.

Value

A list containing the transformed data ($transformed_data), and a function ($trans_new) that can be used to transform grid points and obtain normalizing constants for use in density estimation functions
