fourier_basis: Compute Fourier Basis Expansions

In akreiss/HighDimRD: RDD Estimation Using High-Dimensional Covariates

Compute Fourier Basis Expansions

Description

fourier_basis computes Fourier Bases expansions for the covariates in z up to a given order.

Usage

fourier_basis(z, order)

Arguments

z	n x p Matrix, each column corresponds to one covariate.
order	The order until which the Fourier expansion shall be computed.

Value

n x (2 x p x order) Matrix, each column contains an expression of the form sin(2pirz,i) or cos(2pirz,i) for r=1,...,order and j=1,...,p. The column names are of the form "FB j sin r" or "FB j cos r".
