ols {ddml}

Ordinary least squares.

Description

Simple implementation of ordinary least squares that computes with sparse feature matrices.

Usage

ols(y, X, const = FALSE, w = NULL)

Arguments

y

The outcome variable.

X

The feature matrix.

const

Boolean equal to TRUE if a constant should be included. The default is FALSE

w

A vector of weights for weighted least squares.

Value

ols returns an object of S3 class ols. An object of class ols is a list containing the following components:

coef

A vector with the regression coefficents.

y, X, const, w

Pass-through of the user-provided arguments. See above.
